The system under considerat ion is a static cylindrically-symmetric gravitational configuration in $D$ dimensions in presence of four Abelian 2-forms and four scalar fields. Th e solution is governed by four moduli functions $H_s(z)$ ($s = 1\,...\,4$) of squared radial coordinate $z=\\rho^2$ obeying four differential equati ons of the Toda chain type. These functions turn out to be polynomials of powers $(n_1\,n_2\, n_3\, n_4) = (4\,6\,6\,4)\, (8\,14\,18\,10)\, (7\,12\, 15\,16)\, (6\,10\,6\,6)\, (22\,42\,30\,16)$ for Lie algebras $A_4$\, $B_4$ \, $C_4$\, $D_4$\, $F_4$\, respectively. The asymptotic behaviour for the polynomials at large distances is governed by some integer-valued $4 \\tim es 4$ matrix $\\nu$ connected in a certain way with the inverse Cartan mat rix of the Lie algebra and (in $A_4$ case) the matrix representing a gener ator of the $Z_2$-group of symmetry of the Dynkin diagram. The symmetry pr operties and duality identities for polynomials are obtained\, as well as asymptotic relations for solutions at large distances. We also calculate 2 -form flux integrals over $2$-dimensional discs and corresponding Wilson loop factors over their boundaries.\n\nhttps://indico.particle.mephi.ru/ev ent/35/contributions/2109/ LOCATION:Zoom URL:https://indico.particle.mephi.ru/event/35/contributions/2109/ END:VEVENT BEGIN:VEVENT SUMMARY:The Noble Element Simulation Technique DTSTART;VALUE=DATE-TIME:20201009T141000Z DTEND;VALUE=DATE-TIME:20201009T142500Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2308@cern.ch DESCRIPTION:Speakers: Ekaterina Kozlova ()\nNEST (Noble Element Simulation Technique) is a comprehensive\, semi-empirical standalone package for the complete and accurate simulation of both the scintillation light and ioni zation yields of Xenon and Argon for many particle types (nuclear recoils\ , electron recoils\, alphas\, other interactions) as well as resolution an d pulse shapes.\n\nA significant number of updates to the NEST models\, wh ich substantially improved the package\, are presented.

This is a way to solve the problem of measuring the combined gamma-neutron backgrou nd in a large number of studies: registration of backgrounds near accelera tors\; monitoring of spent nuclear fuel\; monitoring of neutron flux in nu clear fusion installations\; measurement of neutron yield from neutron gen erators.\nScintillation detectors with organic crystals or liquid scintill ators are used for this purposes. The peculiarity of this type of detector is that the pulse shape depends on the type of the detected particle. Tra ditionally\, the Pulse Shape Discrimination (PSD) histogram is used to det ermine the number of detected neutrons. The PSD parameter is calculated fr om the shape of the detector pulse and assigned to each pulse. A typical P SD histogram contains two peaks corresponding to neutrons and gamma rays t hat overlap in the region between the peaks. With this approach\, it is im possible to identify each individual signal in the area between the peaks. Therefore\, it is not possible to calculate the overall signal identifica tion coefficient.\nWe have proposed a new method for the identification of neutrons and gamma quanta\, which includes a combination of three signal separation algorithms: the traditional histogram PSD\, the dependence of t he area of signals on their amplitude\, Tau histogram (tau means the fall constant of the detector pulses). This combination of three algorithms mak es it possible to calculate the value of the signal identification coeffic ient. \nTo test a new method for identifying neutrons and gamma quanta\, w e used a Pu-Be neutron source\, a scintillation detector with a p-terpheny l crystal and a CAEN DT5730 Digitizer (14 bit\, 500 MHz). When a scintilla tion detector registered neutrons from a Pu-Be source\, the signal identif ication coefficient was 89.8%.\nA new method for identifying signals from a scintillation detector is used to register neutrons at the light ion acc elerator.\n\nhttps://indico.particle.mephi.ru/event/35/contributions/2221/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2221/ END:VEVENT BEGIN:VEVENT SUMMARY:A new test-bench design and performance testing of a Low Voltage P ower Supply (LVPS) for the ATLAS Tile Calorimeter front-end electronics DTSTART;VALUE=DATE-TIME:20201005T164500Z DTEND;VALUE=DATE-TIME:20201005T170000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2314@cern.ch DESCRIPTION:Speakers: Edward Khomotso Nkadimeng (University of the Witwate rsrand (ZA))\nWe present test-station designs for testing the latest versi on of a switch-mode power supply for the front-end electronics of the ATLA S hadronic Tile Calorimeter (TileCal) at the LHC.

The diffusion mechanism is usually consider ed as the formation mechanism for Forbush decrease (FD) in a magnetic clou d. An FD is an observed decrease in the intensity of cosmic rays. There is a new theory of FD formation\, in which the mechanism is the loss of part icle energy in the electromagnetic field of a magnetic cloud. The shape of the FD spectrum is calculated for a wide range of particle energies in th e 2004 July 27 event. According to the measurements of the global networks of ground-based neutron monitors and muon telescopes\, synchronous change s in the FD amplitude in time indicate that the FD is formed in a magnetic cloud for all energies. However\, the calculated FD spectrum differs from the obtained one from measurements. The reasons for the difference can be : 1) the mechanism of formation is the diffusion mechanism\; 2) the method for determining the spectrum\, using the notion of mean or median energy\ , needs additional studies.\n\nhttps://indico.particle.mephi.ru/event/35/c ontributions/2216/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2216/ END:VEVENT BEGIN:VEVENT SUMMARY:Neutrino oscillations in long baseline experiments DTSTART;VALUE=DATE-TIME:20201008T101500Z DTEND;VALUE=DATE-TIME:20201008T104500Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2100@cern.ch DESCRIPTION:Speakers: Tsuyoshi NAKAYA (Kyoto University)\nThe discovery of neutrino oscillations and neutrino mass opens a new area in particle phys ics\, astroparticle physics\, and cosmology by studying neutrinos.

Resolving the black hole informati on paradox\, in particular\, can direct us to numerous engrossing discover ies and provide a decent understanding of the unsolved conventional theori es. We readdress the notions underlying the paradox explicitly\, beginning from the basic principles. Various theories\, explanations\, conclusions\ , their advantages and disadvantages in several works of literature regard ing the information paradox and black hole entropy are discussed. Recent d evelopments in the interpretation of the black hole information paradox ar e reviewed. A congenital solution to this contradiction involves the trans ition of classical physics to quantum physics. At the centre of the black hole\, the space-time theory by Einstein’s general theory of relativity fails. The research suggests that the solution obtained from considering t he principles of quantum gravity is quite plausible. This approach also gi ves a decent explanation towards the recondite hypothesis of tunnelling of blackholes to white holes and the interior geometries of white holes.\n\n https://indico.particle.mephi.ru/event/35/contributions/2402/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2402/ END:VEVENT BEGIN:VEVENT SUMMARY:Primordial Black Holes Around Us Now\, Long Before\, and Far away DTSTART;VALUE=DATE-TIME:20201006T101500Z DTEND;VALUE=DATE-TIME:20201006T104500Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2105@cern.ch DESCRIPTION:Speakers: Alexander Dolgov (Novosibirsk State University )\nRe cent astronomical data on Black hole observations are reviewed.

For any DDLES indexes 1 and 2 indicate its first and se cond components\, respectively\, and $М_1/М_2 \\geq 1$. These peaks are created by the populated areas of the coordinated formation of the first a nd second DDLES components. The symmetric separation of one of these popul ated areas into three such areas is found at $M_1/M_2 = 1.0169 \\pm 0.0005 $. The effects are found due to the fact that the formation of the first a nd second DDLES components is coordinated. In this regard\, there is some quantum physical system which creates this coordinated formation. Moreover \, such system exists already before the formation of component bodies fro m baryonic matter. A general gravitational mass of any DDLES is proposed a s the quantum physical system.This gravitational mass is also the measurin g instrument of $M_1$ and $M_2$.Hence\, the formation of the first and sec ond DDLES components begins with the formation of the general gravitationa l mass of their own DDLES.

Re cently\, the theory of NIC revealed a new cosmological phenomenon concerni ng the possibility “gravitons’ entanglement” in the Universe [7]\, t he broad review of which together with new prediction in favor of “initi al cosmic quasi-particles” – mixture of carriers of correlated fundame ntal physical fields in their vacuum states\, has initiated another brave idea. This hypothesis is directly concerning the possibility of the origin al phenomenon on “the large-scale entanglement of prototypes of astropar ticles in the earliest Universe”. \nSince the generation of primary part icles in the rapidly evolving earliest Universe took place in parallel wit h primary substantial fluctuations\, the changing parameters of the initia l prototypes of astroparticles should have significantly differed from tho se steady-state parameters\, which already are experimentally confirmed as characteristic parameters of indiscernible elementary particles of each i dentified family. Consequently\, one may state that the initial fluctuated values of the primary parameters of astroparticles in the form of Gaussia n distributions have been stabilized over time nearby these experimentally confirmed values via cosmological mechanism of large-scale quantum entang lement\, likely realized initially between prototypes of astroparticles.\n Physically it seems very realistic\, that the corresponding time of “co smological standardization process” for each family of proto-particles\, similar to general statistical equilibrium process\, have been extended i n time. Besides still unknown physical essence of such a “stabilizing co smological process”\, it seems intuitively clear that the alleged proces ses of NIC and Modern Physics likely required an incomparably longer perio d of time\, than the Weinberg’s hypothesis on “the first three minutes ”\, accepted in the Modern Cosmology.\nBased on above mentioned\, one ma y manifest that the discovery of new cosmological mechanisms of the creati on and evolution of astroparticles should be studied more deeply and compr ehensively\, using the whole arsenals of Standard Model together with obse rvational data. Of course\, such a scenario at the earliest stages of the evolution of the Universe is able to reveal completely new horizons for th e understanding not only the essence of cosmic objects’ generation scena rio\, but also the essence of the occurring within them original phenomena and processes. \n Above all\, these predictions could have advanced appli cations in galactic SMBH. Indeed\, a quantum entangled and squeezed Bose-c ondensate\, trapped inside the gravitational well of SMBH by means of “i nduced gravitational collapse” [2\,3]\, probably could become large-scal e coherent state which could turn into a more precise\, transparent and ef ficient model for the sought-for source of high energies of galactic core\ , justifying the theoretical mechanism of galactic jet\, previously consid ered in [1] in bare outlines.\n\n \n References \n\n[1] Avetissian A.

The universe which we led life is because of the remaining percenta ges of dark matter and dark energy which is not anti particle or made of d ark material. Most of our universe is hidden in plain sight. Though we can ’t see or touch it\, most astronomers say the majority of the cosmos con sists of dark matter and dark energy. But what is this mysterious\, invisi ble stuff that surrounds us? And what’s the difference between Dark ener gy and Dark matter? In short\, dark matter slows down the expansion of the universe\, while dark energy speeds it up.Dark matter works like an attra ctive force — a kind of cosmic cement that holds our universe together. This is because dark matter does interact with gravity\, but it doesn’t reflect\, absorb or emit light. Meanwhile\, dark energy is a repulsive for ce — a sort of anti-gravity — that drives the universe’s ever-accele rating expansion.\nAstronomers have known that our universe is expanding f or about a century now. Telescopic observations have shown that most galax ies are moving away from each other\, which implies the galaxies were clos er together in the distant past. As a result\, the evidence for the Big Ba ng. However\, astronomers assumed that the combined gravitational pull of all the cosmos’ stars and galaxies should be slowing down the universe ’s expansion. Perhaps it would even someday collapse back in on itself i n a Big Crunch.\nThere are some existence proof for the dark matter theori es like Distance measurements and their relation to redshift\, which sugge st the universe has expanded more in the last half of its life\, The theor etical need for a type of additional energy that is not matter or dark mat ter to form the observationally flat universe (absence of any detectable g lobal curvature)\,Measures of large-scale wave-patterns of mass density in the universe. Since then\, these observations have been corroborated by s everal independent sources. Measurements of the cosmic microwave backgroun d\, gravitational lensing\, and the large-scale structure of the cosmos\, as well as improved measurements of supernovae\, have been consistent with the Lambda-CDM model. Some people argue that the only indications for the existence of dark energy are observations of distance measurements and th eir associated redshifts. Cosmic microwave background anisotropies and bar yon acoustic oscillations serve only to demonstrate that distances to a gi ven redshift are larger than would be expected from a "dusty" Friedmann– Lemaître universe and the local measured Hubble constant. \nSupernovae ar e useful for cosmology because they are excellent standard candles across cosmological distances. They allow researchers to measure the expansion hi story of the universe by looking at the relationship between the distance to an object and its redshift\, which gives how fast it is receding from u s. The relationship is roughly linear\, according to Hubble's law. It is r elatively easy to measure redshift\, but finding the distance to an object is more difficult. Usually\, astronomers use standard candles: objects fo r which the intrinsic brightness\, or absolute magnitude\, is known. This allows the object's distance to be measured from its actual observed brigh tness\, or apparent magnitude. Type I supernovae are the best-known standa rd candles across cosmological distances because of their extreme and cons istent luminosity.\n\nhttps://indico.particle.mephi.ru/event/35/contributi ons/2410/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2410/ END:VEVENT BEGIN:VEVENT SUMMARY:New mK-temperature Germanium detectors for Dark Matter direct sear ch and for precision measurements of CEvNS DTSTART;VALUE=DATE-TIME:20201009T110000Z DTEND;VALUE=DATE-TIME:20201009T113000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2096@cern.ch DESCRIPTION:Speakers: Evgeny Yakushev (JINR\, Dubna)\nIn direct searches f or Dark Matter (DM) a technology developing by EDELWEISS experiment is arr ays of Ge mono-crystal detectors operated at a temperature of few mK and e quipped with electrodes and thermal sensors. Applying a small (few V/cm) e xternal field\, a simultaneous measurement of ionization and heat signals allows efficient identification of nuclear and electron recoils. A larger bias leads to a so-called Neganov-Trofimov-Luke internal amplification of the phonon signal\, lowering the effective threshold and thus opening a se arch at the low energy region not accessible by huge Ar/Xe base detectors. \n\nIn 2020 an unprecedented charge resolution of 0.53 electron-hole pair s (RMS) has been achieved using the Neganov-Trofimov-Luke internal amplifi cation in the EDELWEISS experiment operated at the LSM deep underground si te (France). Thanks to this\, the first Ge-based constraints on sub-MeV DM particles interacting with electrons\, as well as on dark photons down to 1 eV have been set. These results demonstrated the high relevance of cryo genic Ge detectors for the search of DM interactions producing eV-scale si gnals. The region of "light WIMPs" will be further investigated in the EDE LWEISS experiment thanks to advantage of energy resolution below 20 eV rea chable with new array of HPGe bolometers. This stage is in the R&D phase\, building of improved detectors\, their holders and supports\, improvement of the background and acquisition. \n\nThe unlimited target of current R& D and measurements in the EDELWEISS experiment is achievement of sensitivi ty allowing detection of B-8 solar neutrinos through coherent elastic neut rino-nucleus scattering (CEvNS). The same technology and detectors will be applied for precision measurements of CEvNS in the region of full coheren cy in the Ricochet experiment (reactor neutrinos). Due to direct energy re construction (heat signal) the main uncertainty arising due to not well kn own quenching in germanium will be avoided. 1 kg of new cryogenic detector s (developing thanks to joint R&D of EDELWEISS and Ricochet teams) will be integrated in the Ricochet cryostat. The Ricochet is going to be deployed at ILL (Grenoble\, France) site\, on a distance at about 8 m from the 58M W nuclear reactor\, with first results expected to 2025. In addition to th e main goal: precise (1% level) study of CEvNS the experiment will target NMM and other New physics phenomena.

The centrality i s the global characteristic of the nuclear interaction that reflects the d egree of the nuclei overlapping or the number of interacting nucleons. On e of methods to measure the centrality is the determination of the number of non-interacting projectile fragments or spectators\, which have the ver y forward/backward rapidity. In MPD setup these spectators would be detect ed by the two identical hadron calorimeters placed at the opposite sides o f the beam interaction point. Both forward hadron calorimeters (FHCal) hav e the central holes for the beam pipe. The most of heavy fragments escape in these beam holes and are not detected by the calorimeters. As a consequ ence\, the central and peripheral collisions have the same spectator’s e nergy depositions that leads to the ambiguity in the determination of the collision centrality. To resolve this ambiguity a few approaches are devel oped based on the Monte-Carlo simulations with a fragmentation models. In first approach\, the transverse and longitudinal components of the energy depositions in calorimeters are calculated. These two energy components ha ve different correlations for central and peripheral event and can be used for the measurements of the collision centrality. The second approach is based on the subtraction of the pion contamination in FHCal. The number of produced pions is the maximum in the central events and it is minimum in the peripheral ones. The pion energy fraction in FHCal can be subtracted t o accurately measure the spectator’s energy in calorimeters. The accurac y of the centrality measurements with these methods is discussed.\n\nThis work was supported by the Russian Foundation of Basic Research (RFBR) Gran t No. 18-02-40065.\n\nhttps://indico.particle.mephi.ru/event/35/contributi ons/2329/ LOCATION:Zoom Heavy Ion URL:https://indico.particle.mephi.ru/event/35/contributions/2329/ END:VEVENT BEGIN:VEVENT SUMMARY:Primary vertex reconstruction in the BM@N experiment DTSTART;VALUE=DATE-TIME:20201009T144000Z DTEND;VALUE=DATE-TIME:20201009T145500Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2330@cern.ch DESCRIPTION:Speakers: Sergey Merts (JINR)\nThe BM@N (Baryonic Matter at th e Nuclotron) is a working experiment at the NICA (Nuclotron-based Ion Coll ider fAcility) complex.\nThe first physics runs with beams of argon and kr ypton (BM@N setup) as well as with beams of carbon (SRC setup - extension of the BM@N physics program) were carried in 2018.\n\nOne of the prerequis ites for physics analysis of experimental data is the existence of the pri mary vertex position estimation.\nCurrent report describes the proposed al gorithm to reconstruct the primary vertex using the virtual planes method. \nThe results of this algorithm for different targets\, beams and trigger conditions are presented.\nThe sensitivity of presented method to its para meters is considered.\n\nThis work is supported by Russian Foundation for Basic Research grants 18-02-40104 mega and 18-02-40046 mega.\n\nhttps://in dico.particle.mephi.ru/event/35/contributions/2330/ LOCATION:Zoom Heavy Ion URL:https://indico.particle.mephi.ru/event/35/contributions/2330/ END:VEVENT BEGIN:VEVENT SUMMARY:Removal of secondary particle contribution from moments of particl e distributions with Identity Method DTSTART;VALUE=DATE-TIME:20201005T164500Z DTEND;VALUE=DATE-TIME:20201005T170000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2333@cern.ch DESCRIPTION:Speakers: Vitalii Petrov (Saint Petersburg University)\nThe Id entity Method (IM) is a mathematical tool that allows one to solve the pro blem of misidentification in the analysis of moments of particle distribut ions. This method was successfully used for corrections of the first and s econd moments in NA61/SHINE and ALICE experimental data. In this work\, it is shown how the Identity Method could be used in a non-standard way\, na mely\, for correction of the second moments on contamination by secondary particles coming from weak decays and detector material. For that\, distr ibutions of a distance of the closest approach (DCA) of the tracks to the primary vertex are utilized. Thereby\, fluctuations and correlations of pr imary particles can be accessed. Such a correction is essential when there is no inner tracker in an experiment and\, therefore\, a fraction of the secondary particles\, which pass the selection criteria\, is large. In par ticular\, this is relevant for the 1st phase of the MPD experiment.

The currently most co mpelling theoretical descriptions of the mysterious XYZ mesons attribute t hem to hybrid structure with a tightly bound cc\\bar diquark [2] or cq(cq) \\bar tetraquark core [3 - 5] that strongly couples to S-wave DD\\bar mole cular like structures. In this picture\, the production of a XYZ states in high energy hadron collisions and its decays into light hadron plus charm onum final states proceed via the core component of the meson\, while deca ys to pairs of open-charmed mesons proceed via the DD\\bar component.\nThe se ideas have been applied with some success to the XYZ states [2]\, where a detailed calculation finds a cc\\bar core component that is only above 5% of the time with the DD\\bar component (mostly D0D0\\bar) accounting fo r the rest. In this picture these states are compose of three rather dispa rate components: a small charmonium-like cc\\bar core with r_rms 9 fm spa tial extent. Here µ+(µ0) and B+(B0) denote the reduced mass for the D+D- (D0D0\\bar) system and the relevant binding energy |m_D + m_D - M_X(3872) | (B+ = 8.2 MeV\, B0 150 fm [8].\nThe experiments with proton-proton and proton-nuclei collisions with √S_pN up to 26 Gev and luminosity up to 10 ^32 cm^-2s^-1 planned at NICA may be well suited to test this picture for the X(3872) and other XYZ mesons. In near threshold production experiments in the √S_pN ≈ 8 GeV energy range\, XYZ mesons can be produced with t ypical kinetic energies of a few hundred MeV (i.e. with γβ ≈ 0.3). In the case of X(3872)\, its decay length will be greater than 50 fm while th e distance scale for the cc\\bar → D0D*0 transition would be 2 ~ 3 fm. S ince the survival probability of an r_rms ~ 9 fm “molecular” inside nu clear matter should be very small\, XYZ meson production on a nuclear targ et with r_rms ~ 5 fm or more (A ~ 60 or larger) should be strongly quenche d. Thus\, if the hybrid picture is correct\, the atomic number de-pendence of XYZ production at fixed √S_pN should have a dramatically different b ehavior than that of the ψ'\, which is long lived compact charmonium stat e.\nThe current experimental status of XYZ mesons together with hidden cha rm tetraquark can-didates and present simulations what we might expect fro m A-dependence of XYZ mesons in proton-proton and proton-nuclei collisions are summarized.\nReferences\n[1] S.

The relaxation processe s in the extra space metric lead to the establishment of symmetrical extra space configuration and take place during its formation. As a result\, th e initial accumulation of the charges (numbers) associated with the symmet ry occurs. A variant of the mechanism is discussed\, based on triplet spli tting in the ground (massless) Kaluza-Klein level of a fermion field. Such splitting can occur in 2-dimensional apple-like extra space with angle ex cess stabilized by $f(R)$-gravity. This conceptual idea can be used to dev elop a model for the production of the baryon/lepton number in the early U niverse.\n\nhttps://indico.particle.mephi.ru/event/35/contributions/2132/ LOCATION:Zoom URL:https://indico.particle.mephi.ru/event/35/contributions/2132/ END:VEVENT BEGIN:VEVENT SUMMARY:The QCD phase structure at high baryon densities DTSTART;VALUE=DATE-TIME:20201007T141000Z DTEND;VALUE=DATE-TIME:20201007T144000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2456@cern.ch DESCRIPTION:Speakers: Jan Steinheimer (Frankfurt Institute for Advanced St udies)\nhttps://indico.particle.mephi.ru/event/35/contributions/2456/ LOCATION:Zoom Plenary URL:https://indico.particle.mephi.ru/event/35/contributions/2456/ END:VEVENT BEGIN:VEVENT SUMMARY:Expectations for hyperon polarization as a probe of fluid behavior in extreme cases DTSTART;VALUE=DATE-TIME:20201007T130500Z DTEND;VALUE=DATE-TIME:20201007T133500Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2455@cern.ch DESCRIPTION:Speakers: Michael Annan Lisa (Ohio State University\, OH\, USA )\nhttps://indico.particle.mephi.ru/event/35/contributions/2455/ LOCATION:Zoom Plenary URL:https://indico.particle.mephi.ru/event/35/contributions/2455/ END:VEVENT BEGIN:VEVENT SUMMARY:Anisotropic flow measurements from the NA61/SHINE and NA49 beam mo mentum scan programs at the CERN SPS DTSTART;VALUE=DATE-TIME:20201007T151000Z DTEND;VALUE=DATE-TIME:20201007T152500Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2339@cern.ch DESCRIPTION:Speakers: Evgeny Kashirin (National Research Nuclear Universit y MEPhI)\n​The NA61/SHINE experiment at the CERN SPS has recently extend ed its\nprogram for the energy scan with Pb ions.

We have no e xact answer as to why photon\nincarnates itself with versatile mass. Here we try to theoretically\ninvestigate about the rest mass of a photon when it touches the surface\nof matter\, it makes illusion and mathematically t he rest mass is a\ncomplex number that mass dubbed illusive mass.

However\, only very few of them are available and have been studied in theoretical calculations and experimental measurements\, while the rest are generally very interesting\, but their direct implement ation was not feasible. \n\nIn this talk\, I will present a generic recurs ive algorithm for multi-particle cumulants\, which enables the calculation of arbitrary order single and mixed harmonic multi-particle cumulants. Am ong them\, the new 10-\, 12-\, 14-\, and 16-particle cumulants of a single harmonic\, named $c_{n}\\{10\\}$\, $c_{n}\\{12\\}$\, $c_{n}\\{14\\}$\, an d $c_{n}\\{16\\}$\, and the corresponding $v_n$ coefficients\, will be dis cussed for the first time.

Finally\ , I will propose a particular series of mixed harmonic multi-particle cumu lants\, which measures the general correlations between any moments of dif ferent flow coefficients. The study of these new multi-particle cumulants in heavy-ion collisions will significantly improve the understanding of th e joint probability density function which involves both different harmoni cs of flow and also the symmetry planes. This will pave the way for more s tringent constraints on the initial state and help to extract more precise ly information on how the created hot and dense matter evolves.

These particles are i nvisible until they decay into detectable Standard Model particles some ma croscopic distance away from the collision. Their existence is theoretical ly well motivated and can provide explanations to known unexplained phenom ena such as Dark Matter\, the Baryon Asymmetry of the universe\, neutrino masses\, and the Hierarchy Problem. The current LHC search programs focus mostly on energetic final states produced promptly within subatomic distan ces of the proton collision. These searches are largely insensitive to neu tral LLPs. An LLP surface detector may be the only way of discovering new physics and\, by that\, solving fundamental puzzles of the incomplete Stan dard Model. These considerations prompt the MATHUSLA experiment (MAssive T iming Hodoscope for Ultra-Stable neutraL pArticles)\, which opens a new av enue for discovery of Physics Beyond the Standard Model at the LHC. The la rge-volume detector will be placed above the CMS experiment with O(100) m of rock separation from the LHC interaction point. It is instrumented wit h a tracking system to observe LLP decays inside its empty volume. The exp eriment is composed of a modular array of detectors covering together (100 × 100) m$^2$ × 25 m high. It is planned in time for the high luminosity LHC runs. \n\nMATHUSLA\, with a large detection area and good granularity tracking system\, is also an efficient cosmic-ray Extensive Air Shower (E AS) detector. It could reach a very good time\, spatial and angular resolu tion\, and the several tracking layers might allow performing very precise cosmic-ray measurements up to the PeV scale.\n \nWe will describe the det ector concept and layout\, the current status of the project\, the on-goin g cosmic ray studies\, as well as the future plans.

It is related to the slope of the electric form factor of the proton $ G_{pE} (q) $ at $ q^2 = 0 $. Over the past two decades\, ato mic laser spectroscopy has proven to be a powerful tool for determining th e charge radii of light nuclei. Atomic spectroscopy of hydrogen is an indi rect way of determining the charge radius $ r_{pE} $ of a proton from pres ision measurements of certain energy intervals. While electron scattering and spectroscopy of electron atoms have been available for a long time\, m uon spectroscopy became available only in 2010 due to the work of the CREM A collaboration. As a result of the first CREMA experiments in 2010\, the value $ r_{pE} = 0.84184 (67) $ fm was obtained\, which was 10 times more accurate than all previous values from experiments with electronic systems . Moreover\, this value was significantly less than the CODATA value\, $ r _{pE} = 0.8768 (69) $ fm. This difference is called the "puzzle" of the pr oton radius. In this work\, a precision study of the structure of energy l evels of S-states of hydrogen in quantum electrodynamics is carried out ta king into account corrections for vacuum polarization\, nuclear structure\ , relativism\, as well as complex combined corrections that include the ab ove. The frequency of the transition between the levels of S-states is cal culated\, which is necessary for comparison with the corresponding experim ental data.\n\nhttps://indico.particle.mephi.ru/event/35/contributions/213 7/ LOCATION:Zoom HEP Theory URL:https://indico.particle.mephi.ru/event/35/contributions/2137/ END:VEVENT BEGIN:VEVENT SUMMARY:On mass limits for scalar color octet from the LHC data on tttt an d tbtb production.

The effects of the string fusion are taken into account by introducing a finite latti ce (a grid) in the impact parameter plane [4].

Suleymanli (National Research Nuclear Univ ersity MEPhI)\nJosephson current between two one-dimensional nanowires wit h proximity induced either s-wave or p-wave pairing and separated by a nar row dielectric barrier is calculated in the presence of Rashba spin-orbit interaction (RSOI)\, in-plane and normal Zeeman magnetic fields (ZMF). A t opological superconducting phase in a Josephson junction of s-wave superco nductors (s-JJ) is realized under the condition $|∆|^2 > B^2 + h^2$\, wh ere Δ\, B\, and h are correspondingly the gap\, Zeeman energy of in-plane and normal magnetic fields. Instead\, the condition $∆_k = \\frac{\\vec {k}}{|k|}∆_0$ guarantees an existence of a conducting state in the gap a nd realization of a generic topological phase of the p-wave superconductor (p-JJ). Andreev retro-reflection is shown to be realized through two diff erent channels. A scattering in a conventional particle-hole channel\, whe n an electron-like quasi-particle reflects to a hole-like quasi-particle w ith opposite spins\, provides the current which depends only on the order parameters’ phase differences ϕ\, and oscillates fractionally with 4 π period. Fractional oscillation of the current with 4π period is the ma in manifestation of realization of Majorana fermion in the system. Second anomalous particle-hole channel\, corresponding to the Andreev reflection of an incident electron-like quasiparticle to hole-like quasiparticle wit h the same spin orientation\, survives only in the presence of the in-plan e magnetic field. The contribution of this channel to the Josephson curre nt oscillates with 4π period not only with ϕ but also with orientational angle of the in-plane magnetic field θ resulting in a magneto-Josephson effect. RSOI and ZMF are shown to split the quasi-electron and quasi-hol e excitation states in the superconducting gap\, and two quasi-particle an d quasi-hole pairs instead of one pair appear in the gap\, which are local ized symmetrically around Fermi level. ZMF is shown to destroy this symmet ry. Even in the absence of the magnetic fields in s-JJ the energy gap be tween the Andreev bound states decreases with increasing RSOI. Investigati on of ac-Josephson current in s-JJ shows that the width of the resulting S hapiro steps in such a system can be tuned by varying the RSOI constant. I n the presence of RSOC and normal-to-plane magnetic field h in p-JJ\, a f orbidden gap is shown to open in the dependence of Andreev bound state ene rgies on the phases ϕ and θ at several values of RSOC strength and ZMF\, where Josephson current seems to vanish [1]. \n\nReferences:\n\n[1] E.

The medium mod ified masses of kaons and antikaons\, which are used as input in AMPT mode l\, are calculated using the chiral SU(3) mean field model. Within chiral SU(3) model along with the Weinberg Tomozawa term\, the contribution of ex plicit symmetry breaking term and three range terms is incorporated to stu dy their impact on the above listed experimental observables. The repulsiv e contribution to the masses of K+ meson from the Weinberg term and one ra nge term dominate over the attractive contribution from explicit symmetry breaking as well as other two range terms. For the K- meson repulsive cont ribution comes from first range terms only whereas all other terms have at tractive contribution. Considering all these features from chiral effectiv e model on properties of K+ and K- mesons\, we explore the splitting in th e flow of kaons and antikaons.\n\nhttps://indico.particle.mephi.ru/event/3 5/contributions/2147/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2147/ END:VEVENT BEGIN:VEVENT SUMMARY:Taking into account the random component in the quantum representa tion of particles DTSTART;VALUE=DATE-TIME:20201005T164500Z DTEND;VALUE=DATE-TIME:20201005T170000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2148@cern.ch DESCRIPTION:Speakers: Victor Vorontsov (NRNU MEPhI)\nDynamic chaos is obse rved experimentally in macro objects\, but did not receive a proper explan ation. To take it into account in the quantum representation of the partic le motion\, an attempt was made to introduce a random component into the e quation of motion. Its magnitude depends on the intrinsic energy of the pa rticle\, equal to the resting energy. The total energy of the particle is equal to the sum of the deterministic and random energy. The deterministic energy of the particle is equal to the kinetic energy of the particle and the energy of the field in which it is located. The dynamics of the parti cle movement is considered in a quantum representation. A system of ordina ry differential equations in finite differences is obtained. The principle of minimal action is carried out without taking into account the random c omponent of the movement and without taking into account the second bounda ry condition. The division of motion into deterministic and random compone nts is also random. The calculation technique was tested on data depicting the movement of an electron in in a hydrogen atom around its nucleus in t he form of a proton. Estimates showed a satisfactory coincidence of calcul ated and experimental data. Quantum approximation was also used to infer a number of equations of physics. It includes the derivation of the equatio ns of classical mechanics describing translational and rotational movement s. Then\, in the same way\, the equations of classical electrodynamics bea ring the name Maxwell were deduced. This was followed by the conclusion of the equation of non-relativistic quantum mechanics\, called the Schroding er equation. Then the equation of relativistic quantum mechanics\, known a s the Klein Gordon equation\, was derived. Finally\, the same approach was used to infer the first onset of thermodynamics.\n\nhttps://indico.partic le.mephi.ru/event/35/contributions/2148/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2148/ END:VEVENT BEGIN:VEVENT SUMMARY:Searches for new phenomena in final states involving leptons and j ets using the ATLAS detector DTSTART;VALUE=DATE-TIME:20201007T161500Z DTEND;VALUE=DATE-TIME:20201007T163500Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2377@cern.ch DESCRIPTION:Speakers: Andrej Gorisek (J.

A pa rticular focus is given to searches for leptoquarks (LQ) that offer an att ractive potential explanation for the lepton flavour anomalies seen at fla vour factories and vector like quarks (VLQ) that in turn offer an attracti ve solution for the hierarchy problem. Improved multivariate methods fo r identifying heavy quarks will also be highlighted.\n\nhttps://indico.par ticle.mephi.ru/event/35/contributions/2377/ LOCATION:Zoom HEP URL:https://indico.particle.mephi.ru/event/35/contributions/2377/ END:VEVENT BEGIN:VEVENT SUMMARY:BSM contributions to the Z gamma gamma and ZZ gamma self couplings at hight energies DTSTART;VALUE=DATE-TIME:20201005T164500Z DTEND;VALUE=DATE-TIME:20201005T170000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2149@cern.ch DESCRIPTION:Speakers: Айрат Камалетдинов ()\nThe Z \\gamm a \\gamma and ZZ \\gamma couplings in the SM and MSSM models were investig ated.

It was extensively studied in hadronic reactions\, where it is di rected along the normal to the scattering plane. In heavy-ion collisions t his observable is expected to decrease due to randomization of the scatter ing on different nucleons. At the same time\, there exist another observab le\, global hyperon polarization\, which is directed along the normal to t he reaction plane. It is emerging due to the presence of initial angular m omentum in non-central heavy-ion collisions and is growing with decreasing energy. The goal of future MPD and BM@N experiments at NICA is to investi gate these observables in heavy-ion collisions in the energy range of seve ral GeV per nucleon.

The ions of muonic lithium (µ e Li)\, berylli um (µ e Be)\, and boron (µ e B) include the simplest light nuclei behind hydrogen and helium. The lifetime of such ions is determined by the lifet ime of the negative muon. These bound states have a complex energy structu re\, which arises as a result of the Coulomb interaction of particles\, as well as the interaction of their magnetic moments. The interest in these systems is due to the fact that the composite particles in them have very different masses. As a result\, the muon and the nucleus form a quasi-nucl eus around which the electron moves\, and the three-particle system itself looks\, in the first approximation\, like a two-particle atom. The electr onic excited states 2S and 2P in such atoms can be investigated experiment ally. In any case\, such a program already exists for the muonic helium at om (µ e He).

Precise event -by-event estimate of these basic observables is crucial for many physics phenomena studies to be performed by the NA61 Collaboration. The PSD is a modular compensating lead-scintillator calorimeter designed to measure the energy distribution of the projectile nuclei fragments (spectators) and f orward going particles produced close to the beam rapidity. Each module of the PSD has a lead-scintillator sandwich structure with longitudinal segm entation. A scintillator light readout is provided by WLS-fibers and by si licon photomultipliers (micropixel avalanche photodiodes).\n In order to fulfill the future requirements for NA61/SHINE experiment upgrade the PSD has been re-designed.

It can lead to the formation of a local parity breaking LPB in a quark-hadron medium and adiabatically characterized by a topological cha rge and\, accordingly\, a topological (chiral) chemical potential $\\mu_5$ . In the field theory\, it can be considered as a time-like axial-vector $ b_\\mu$ coupled to a fermion field with its zero component associated with $\\mu_5$. The consistent way for the construction of the Lagrangian in th e presence of constant axial-vector background has been obtained in [1\, 2 ] for QED theory.\n\nIn this report\, for the description of the propertie s of light vector mesons in the presence of LPB in a fireball\, the vector -meson dominance model is applied in the lightest SU(2) sector. Employing the approach\, developed in [1\, 2]\, to the vector $\\rho$ and $\\omega$ mesons\, we obtain the mass spectrum as a function of momentum and chiral chemical potential $\\mu_5$. We show that in addition to the Chern–Simon s term [3]\, splitting the transverse polarisations of the mesons\, there is an additional contribution that becomes important at momentum and $\\mu _5$ around a few hundred MeV.\n\n\nReferences:\n\n[1] J.

It is necessary to inv estigate the processes of explosive release of energy and acceleration of charged particles occurring in the solar corona for really occurred flares . During a solar flare in the solar corona above the active region (AR)\, the energy stored in the magnetic field of the current sheet is released. The current sheet is formed in the vicinity of a singular X-type line in t he magnetic field of the solar corona as a result of the accumulation of d isturbances propagating from the solar surface. \nNumerical magnetohydrody namic (MHD) simulation in the corona\, when all conditions are taken from observations and no assumptions about the flare mechanism are done in adva nce\, confirmed the current sheet mechanism. Using the results of numerica l simulation and observations\, I.M. Podgorny proposed an electrodynamic m odel of a solar flare\, explaining its main observational manifestations\, in particular\, the appearance of X-ray emission on the surface of the Su n. The acceleration of protons occurs along a singular line of the magneti c field of the current sheet by the electric field $ {\\bf E} = -\n{\\bf V } \\times {\\bf B} /c$\, which increases during the instability of the cur rent sheet. This mechanism of solar cosmic rays generation is confirmed by comparing the spectrum found by calculating the proton trajectories in th e electric and magnetic fields obtained by MHD modeling with the spectrum obtained from the data of the worldwide network of neutron monitors. In or der to get rid of the instability distorting the numerical solution caused by the unnaturally rapid change in the magnetic field at the photospheric boundary with the previously performed MHD simulation in the in the reduc ed scale of time\, it is necessary to carry out MHD simulation in the real scale of time. Also\, such a simulation is necessary for a more accurate study of the acceleration of charged particles and the possibility of thei r exit from the region of a strong magnetic field by calculating the parti cle trajectories in the electric and magnetic fields obtained by MHD simul ation. MHD simulation in the solar corona above AR in the real scale of ti me can only be done using parallel computing on a supercomputer. The paral lelization of the program PERESVET for numerical solving MHD equations of in two ways was carried out. Parallel computing with an OpenMP system uses many computer processor (CPU) threads. The most effective parallel comput ations were carried out using CUDA technology using graphics card (GPU) pr ocessors specially adapted for parallel computations. After a series of op timizations of the data exchange processes between the GPU memory and the memory of the CPU\, the calculations for numerical solution of the MHD equ ations were accelerated by ~ 40-50 times. As a result of optimization of t he approximation of the boundary conditions of free exit at the non-photos pheric boundary\, at which the plasma velocity near the boundary is signif icantly reduced\, instability near the boundary\, which previously hindere d the numerical solution\, was stabilized. The first results of MHD simula tion in the real scale of time above the AR 10365 showed the appearance of a plasma flow near singular X-type lines\, which have to cause to the for mation of a current sheet. MHD simulation in the corona above the AR 10365 in the real scale of time and further optimization of the parallel comput ing method using CUDA technology for the numerical solution of MHD equatio ns continues.\n\nhttps://indico.particle.mephi.ru/event/35/contributions/2 170/ LOCATION:Zoom Astroparticle URL:https://indico.particle.mephi.ru/event/35/contributions/2170/ END:VEVENT BEGIN:VEVENT SUMMARY:First detection of gamma-ray sources at TeV energies with the firs t imaging air Cherenkov telescope of the TAIGA installation DTSTART;VALUE=DATE-TIME:20201009T154000Z DTEND;VALUE=DATE-TIME:20201009T155500Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2174@cern.ch DESCRIPTION:Speakers: Evgeny Postnikov (SINP MSU)\nTAIGA array (Tunka Adva nced Instrument for cosmic ray physics and Gamma-ray Astronomy) addresses gamma-ray astronomy at energies from a few TeV to several PeV as well as c osmic ray physics from 100 TeV to several EeV.

Kazalov (INR RAS)\nThe fundamental difference b etween low-background nuclear-physical measurements and other types of stu dies of the characteristics of ionizing radiation sources is the extremely low total event count rate. Therefore\, all recording devices in such exp eriments are oriented to work with individual signals. Spectrometric measu rements of low-energy ionizing radiation using gas detectors are mainly ca rried out in the proportional amplification mode. The proportional counter is an excellent detector for the soft x-ray region because it is saturabl e\, energy selective and has high-absorption efficiency as well as a very good signal to noise ratio. The search for such a rare nuclear decay as th e simultaneous capture of two orbital electrons by the same noble gas isot ope nucleus by recording x-rays and Auger electrons is possible using larg e proportional counters. The characteristics of these counters must satisf y a number of conditions\, since the intrinsic radiation\, a background of the detectors must be ultra-low and the spectrometric characteristics mus t be stable during sufficiently long measurements. \n\nModern equipment al lows us to record the full shape of the signals in digital form from sever al channels simultaneously. Subsequent analysis with specially developed s oftware algorithms allows obtain the desired dependencies and divide event s into separate groups. Such information is of particular value when condu cting low-background measurements\, in which the useful effect is a small fraction of the total count rate. In this case\, the selection of events w ith parameters corresponding to the effect can significantly increase the effect/background ratio. The quality of such a selection depends on the co mpleteness of taking into account the features of the response function to the desired events inherent in a particular operating mode of the gas det ector.\n\nExperiments on the study of double decay processes with the capt ure of electrons of the inner atomic shell in different isotopes of high-p urity noble gases are ongoing for a long time at the Baksan Neutrino Obser vatory of the INR RAS using several 10.93-liter copper proportional counte rs. The experience of long-term measurements related to a search of 2$\\nu $2K capture with samples of different enriched for $^{78}$Kr and $^{124}$X e using large proportional counters with a casing made of M1-grade copper showed that the spectrometric properties of the detector quite noticeably degrade over time.\n\nIn this report\, we will focus on the analysis of ch anges in spectrometric properties overtime of a detector filled with xenon during long measurements\, in contrast to krypton\, which does not have l ong-lived radioactive isotopes that allow enough proper calibration from i nternal sources.\n\nhttps://indico.particle.mephi.ru/event/35/contribution s/2280/ LOCATION:Zoom Facilities URL:https://indico.particle.mephi.ru/event/35/contributions/2280/ END:VEVENT BEGIN:VEVENT SUMMARY:Dark matter searches by the planned gamma-ray telescope GAMMA-400 DTSTART;VALUE=DATE-TIME:20201006T152500Z DTEND;VALUE=DATE-TIME:20201006T154000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2178@cern.ch DESCRIPTION:Speakers: Andrey Egorov (Lebedev Physical Institute)\nOur work reviews the planned space-based gamma-ray telescope GAMMA-400 and evaluat es in details its opportunities in the field of dark matter (DM) indirect searches.

The hun dred particle tracks in x-ray films have been re-analyzed in the style of LHC experiments: rapidity distributions of charged particles and transvers e mass spectra of multiparticle production have been built. The comparison of multiple rapidity-and-Mt histograms with the knowledge accumulated in the Quark-Gluon String Model gives us the conclusion that it was the carbo n nucleus collision with a matter of atmosphere at the c.m.s. equivalent e nergy 5 TeV. After QGSM analysis of these scarce data\, we know the follow ing: 1) the value of maximal rapidity of one projectile proton and 2) the density of particle multiplicity in the central rapidity region.

They approched the Earth in October 2017 and in December 2019 respe ctively. A gamma-ray emission is expected from these objects due to inter action of Cosmic Rays (CRs) with their surfaces\, while more exotic models predict possible gamma-rays due to accelerated particles or dark matter. We searched for a gamma-ray emission with the Fermi Large Area Telescope ( LAT)\, focusing on the period around the minimum distance from Earth. Two independent analysis were performed\, taking into account the path of the two objects moving in the sky. The first method consists in an ON/OFF like lihood analysis of the signal and background regions\, while the second is based on a quasi static point source likelihood analysis. No significant signal was found and upper limits on the gamma-ray flux were derived.

An excess of muons appear s in the energy range of the extensive air showers (EAS) above 10^17 eV. T he answer to the “muon puzzle” may be found by means of the study of t he energy characteristics of the muon component of EAS in a wide range of primary particle energies (from 10^16 to 10^18 eV). For this purpose\, in the NEVOD-DECOR experiment the measurements of the energy deposit of muon bundles in the detector material have been carried out. The installation i ncludes a Cherenkov water calorimeter NEVOD with a volume of 2000 cubic me ters and coordinate-tracking detector DECOR with an area of 70 square mete rs. The energy deposit of muon bundles is determined from the response of the Cherenkov water calorimeter\, and the coordinate-tracking detector all ows one to determine the local density of muons in the bundles and the dir ection of their arrival\, and hence to estimate the energy of the primary particle. The results of measurements of the muon bundle energy deposit in inclined showers over several years of observations are presented. The ex perimental dependences of the energy deposit of muon bundles are compared with the results of simulations performed with the CORSIKA software packag e using modern models of hadronic interactions.\n\nhttps://indico.particle .mephi.ru/event/35/contributions/2191/ LOCATION:Zoom Astroparticle URL:https://indico.particle.mephi.ru/event/35/contributions/2191/ END:VEVENT BEGIN:VEVENT SUMMARY:Study of Plastic Scintillator Detector for the High Energy cosmic- Radiation Detection (HERD) experiment DTSTART;VALUE=DATE-TIME:20201006T142500Z DTEND;VALUE=DATE-TIME:20201006T144000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2192@cern.ch DESCRIPTION:Speakers: Leonardo Di Venere (INFN Bari)\nThe High Energy Cosm ic Radiation Detection (HERD) facility proposed onboard the future Chinese Space Station (CSS) in 2026 will provide high-quality data on charged cos mic rays and gamma rays from GeV to PeV energies.

Our analysis is based on the observational fact of the existe nce of three pulsars reaching this limit and on the theoretically predicte d reduction of the neutron star maximal mass caused by the accumulation of dark matter in its interior. We also demonstrate that light dark matter p articles with masses below 0.2 GeV can create an extended halo around the neutron star leading not to decrease\, but to increase of its visible grav itational mass. By using recent results on the spatial distribution of dar k matter in the Milky Way\, we present an estimate of its fraction inside the neutron stars located in the Galaxy center. We show how the detection of a 2Msun neutron star in the most central region of the Galaxy will impo se an upper constraint on the mass of dark matter particles of ∼ 60 GeV. Future high precision measurements\nof the neutron stars maximal mass nea r the Galactic center\, will put a more stringent constraint on the mass o f the dark matter particle.

TAIGA aims to addresses gamma-ray astronomy at energies from a few TeV to several PeV\, as well as cosmic ray physics from 100 TeV to several EeV and astop article physics problems. For the energy range 30 – 200 TeV the sensitiv ity of 10 km^2 area TAIGA detector for the detection of local sources is expected to be 10^{−13} erg cm^{−2} sec^{−1} for 300 h of observati ons. Combination of the wide angle Cherenkov timing detector TAIGA-HiSCOR E with the 4-m class Imaging Atmospheric Cherenkov Telescopes (TAIGA-IACT ) of FoV of 10x10 degrees offers a cost effective-way to construct a 10 km^2 array. Reconstruction of a given EAS energy\, incoming direction and its core position\, based on the TAIGA-HiSCORE data allow one to increase a distance between the IACTs up to 600-1000 m. The low investments toge ther with the high sensitivity for energies ≥ 30-50 TeV make this pionee ring technique very attractive for exploring the galactic PeVatrons and co smic rays. In addition to the Cherenkov light detectors we intend to deplo y an array of muon detectors (TAIGA-Muon array) spread over an area of 1 km^2 with a total area of about 2000 m^2.

The curvature of the orbit is determined by the action of the electri c field of a practically fixed proton on a moving electron. A flat case is considered when the orbit circumference lies in a fixed plane of rotation . The trajectory of the electron is a broken line consisting of equal segm ents. The lengths of the segments are determined from the relation of unce rtainties for the pulse and coordinates. The pulse is equal to the mass of the electron multiplied by the speed of light. It is assumed that the eoe ctron phase periodically transitions from state (E\, t) to state (p\, r). The increment of the pulse under the action of an electric field in the di rection orthogonal to the electron pulse is equal to the quotient of divid ing the Planck constant by the electron rest energy. Random component is e xcluded for simplicity. The trajectory of the electron turns into a polygo n. The same approach was used to quantize the dynamics of the electron in the condenser. The radiation was simulated by turning the orthogonal pulse gain when it was rotated in a magnetic field\, resulting in shortening of the electron pulse. This shortening led to the transition of part of the kinetic energy of the electron into radiation. Thus\, it is shown that the given simplified quantization mechanism can be applied to electron dynami cs\, both without radiation and with radiation.\n\nhttps://indico.particle .mephi.ru/event/35/contributions/2201/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2201/ END:VEVENT BEGIN:VEVENT SUMMARY:Status and future of neutrino astronomy and the Global Neutrino Ne twork DTSTART;VALUE=DATE-TIME:20201008T153500Z DTEND;VALUE=DATE-TIME:20201008T155000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2246@cern.ch DESCRIPTION:Speakers: Christian Spiering (MEPhI/DESY)\nThe discovery of co smic neutrinos with IceCube has opened a new window on the universe.

The Forbush decreases (FD)\, arising from the influence of solar activity on the flux of cosmic rays\, as well as the lunar cycles associa ted with an increase of the release of radioactive radon due to the occurr ence of a lunar tidal wave\, were studied.\n\nThe “Neutron” setup\, wh ich is a part of the Experimental Complex NEVOD (MEPhI\, Moscow)\, is desi gned to register the thermal neutrons flux on the Earth's surface. It is i n operation in a continuous mode since 2010. The setup includes four ident ical neutron detectors based on the inorganic scintillator 6LiF+ZnS (Ag). Due to the different location of the detectors (from – 3 m to 10.5 m rel ative the ground surface) and their high sensitivity to thermal neutrons\, it was possible to study various phenomena that affect the background neu tron flux near the surface. The counting rate of each detector was correct ed for the barometric pressure effect.\n\nAs a result of the analysis of t he setup data during the specified period\, 20 FD were found\, for each of them the FD amplitude and recovery time were estimated. The comparison wi th the results of FD studies in data of two other setups: the Moscow neutr on monitor (MNM) and the muon hodoscope URAGAN (MEPhI\, Moscow) was made. Comparison showed that the FD amplitudes of "Neutron" are comparable with those of MNM (on average\, less by about 30%)\, and about 1.5 times more t han for URAGAN.

The review is dedicated to the 90th anniversary of the outstanding experim ental physicist Boris Anatolyevich Dolgoshein\, in whose laboratory exactl y 50 years ago the first two-phase emission detector has been created.\nTo day two-phase emission detectors found the best application in the most se nsitive at the moment experiments searching for cold dark matter in the fo rm of weakly interacting massive particles (WIMPs). A number of successful experiments arranged by ZEPLIN\, XENON\, LUX and PandaX collaborations wi th LXe emission detectors during 10 years period reduced allowed region of existence for WIMPs with mass of 40-50 GeV/c2 from 8.810-44cm2 (report ed by XENON-10 collaboration in 2006) down to 1.110-46cm2 (reported by LUX collaboration at the end of 2016). Detector LZ of the second generatio n (G2) will be installed at Davis’ cage of the Homestake mine by joint c ollaboration of former LUX and ZEPLIN experiments and will use 6 ton LXe a ctive mass emission detector in order to reach sensitivity below 10-47 cm2 for spin-independent WIMP-nucleon interactions. With the increasing detec tor mass and sensitivity\, solar neutrino interactions become an irreducib le source of background for WIMP search experiments. Multi-ton active mass WIMP detectors of the upcoming G3 generation shall become\, even with nat urally occurring isotope abundances\, sensitive to double-beta decay at th e modern level of sensitivity and solar neutrinos interactions via elastic coherent scattering off xenon nuclei. Detectors of G3 generation such as DarkSide-20k can achieve spin-independent cross sections for WIMPs as low as ~ 7.410-48cm2 (6.910-47cm2) for WIMPs of 1TeV/c2 (10TeV/c2 ) mass . \nThe RED-100 detector constructed at NRNU MEPhI can be used for invest igation of recently discovered the elastic coherent electron neutrino scat tering off heavy nuclei. The detector can be installed practically on the Earth's surface in vicinity to low energy neutrino sources such as NPP nuc lear reactors or accelerators such as the Spallation Neutron Source. \nThe new LBNO (Long Baseline Neutrino Observatory) experiment intends to use l arge Liquid Argon (LAr) double-phase time projection chamber (DLAr TPC) as one of the detectors. The consortium at CERN is now active in the constru ction of a large demonstrator LBNO-DEMO DLAr TPC of 3x3x1 m3 active volume .\nThus the detector technology invented at MEPhI 50 years has demonstrate d a great potential to be used in a variety of fundamental research progra ms.\n\nhttps://indico.particle.mephi.ru/event/35/contributions/2107/ LOCATION:Zoom Plenary URL:https://indico.particle.mephi.ru/event/35/contributions/2107/ END:VEVENT BEGIN:VEVENT SUMMARY:On the nature of particles that produces extensive air showers wit h energires greater than 5 EeV DTSTART;VALUE=DATE-TIME:20201005T164500Z DTEND;VALUE=DATE-TIME:20201005T170000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2210@cern.ch DESCRIPTION:Speakers: Igor Petrov (Yu. G. Shafer Institute of Cosmophysica l Research and Aeronomy)\nIn the physics of cosmic rays\, there has always been a question about the primary particles that generate extensive air s howers. This was especially true for particles with highest energies\, sin ce it is unclear nature of sources and mechanisms in outer space that prod uces such particles. \n\nTo study the nature of particles with energies gr eater than 5 EeV\, the database of the Yakutsk array was analyzed. The exp eriment has been operating continuously for 50 years\, and during this per iod\, unique material has been collected on the main components of air sho wers: the electron-photon component\, muons\, Cherenkov and radio emission s. Showers coming one after the other are highlighted (let’s call them “double showers”) within a time interval of 1-20 hours. Some periodici ty was found in the registration of such showers during the daily observat ion cycle with an average time of T = 6-8 hours. The characteristics of th e selected showers: energy\, zenith and azimuthal angles were found to be close in magnitude. Consequently\, we can assume the same origin nature of the primary particles that initiate such EASs. The existing discrepancy i n the arrival time of showers at the Earth's level can be attributed to th e participation in various processes in outer space: the interaction of pa rticles with different charges with galactic magnetic field\, acceleration of particles due to the frictional mechanism\, followed by re-emission wi th higher energy\, and time delay at the shock front. If this hypothesis i s correct\, then the analysis of such air shower events will make it possi ble to obtain information on the processes of interaction of shock waves w ith the matter of the Universe.\n\nThe other possibility is that particles can be produced due to surfing of charged particles on electromagnetic wa ves\, which is one of the main and effective mechanisms for generating jet s of ultrarelativistic particles with energies $10^9$-$10^{22}$ eV in cosm ic plasma. The other possibility is that the particles can be produced in pairs during the interaction of protons with the cosmic microwave backgrou nd – the GZK effect. Then one should expect double showers produced by t wo gamma rays. An analysis of the muon component in these events can provi de an answer to this question.\n\nhttps://indico.particle.mephi.ru/event/3 5/contributions/2210/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2210/ END:VEVENT BEGIN:VEVENT SUMMARY:Mirror aligment of TAIGA-IACT telescopes using the Bokeh effect DTSTART;VALUE=DATE-TIME:20201005T164500Z DTEND;VALUE=DATE-TIME:20201005T170000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2211@cern.ch DESCRIPTION:Speakers: Alexandra Ivanova (Denisovna)\nThe TAIGA Gamma-Obser vatory is a new hybrid detector\, located in the Tunka Valley.

Calculations of the fraction of muons are performe d using the QGSjetII-04 hadronic interaction model for different primary n uclei\, and compared with the data. Mass composition of primary particles is estimated by muon component. Several showers were found in the sample\, with a low content of muons\, which possibly is produced by ultrahigh ene rgy gamma rays.\n\nhttps://indico.particle.mephi.ru/event/35/contributions /2212/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2212/ END:VEVENT BEGIN:VEVENT SUMMARY:Rigidity dependences of the main characteristics of Forbush decrea ses DTSTART;VALUE=DATE-TIME:20201005T164500Z DTEND;VALUE=DATE-TIME:20201005T170000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2213@cern.ch DESCRIPTION:Speakers: Iliya Lagoida (Moscow Engineering Physics Institute) \nForbush decrease (FD) is an effect in the cosmic ray physics which is ch aracterized by sharp short-term decreases in cosmic ray intensities record ed by satellite and ground-based instruments. Nowadays it is well establis hed that coronal mass ejections (CMEs) are the main drivers of FD. A huge amount of solar plasma is thrown into interplanetary space during CMEs. Th is plasma propagates outwards from the Sun with a magnetic field frozen in to it. These moving structures are known as interplanetary coronal mass ej ections (ICMEs). ICMEs modulate cosmic ray particles causing FDs. Today th e properties of FDs are studied mostly by ground based detectors such as n eutron monitors and muon godoscopes. These detectors are characterized by high event statistics\, but register intensity of secondary cosmic rays. I n this work rigidity dependencies of amplitudes and recovery times of FDs obtained by the PAMELA experiment are presented.

However\, when operating with a scintillation detector near par ticle accelerators\, there is a problem associated with the presence of a magnetic field near the accelerator.\nA new efficient detector for mixed n eutron and gamma fields is installed at the HELIS accelerator facility. Th is scintillation detector contains an organic crystal p-terphenyl and a Ha mamatsu R6094 photomultiplier tube (PMT). The signals from the PMT output are digitized using a Flash Digitizer (14 bit\, 500 MHz). USB interface em bedded in to the Digitizer is used to communicate with the personal comput er. \nWe studied the effect of the magnetic field of the HELIS accelerator facility on the parameters of the scintillation detector signals and on t he efficiency of separating signals from neutrons and gamma quanta.\nCs-13 7 and Co-60 gamma sources were used to study changes in the amplitude and shape of the detector signals for different positions of the PMT’s dynod e system relative to the magnetic field. The dependences of the amplitude and shape of the signals on the magnitude of the magnetic field are presen ted. It is shown that the magnetic field leads to a decrease in the amplit ude and distortion of the signal shape.\nUsing the Cf-252 neutron source\, the efficiency of separating signals from neutrons and gamma quanta depen ding on the magnitude of the magnetic field was studied. Figure of Merit ( FOM) is a measure of the efficiency of separating signals from neutrons an d gamma rays.\nIn the absence of a magnetic field\, the efficiency of sign al separation is FOM = 1.5. When a magnetic field is 0.5 mT\, the signal s eparation efficiency decreases to FOM = 1. If a magnetic field is equal to ≈ 1 mT\, it becomes impossible to separate the signals from neutrons an d gamma quanta. The use of a PMT with a magnetic shield made of an amorpho us alloy makes it possible to separate neutrons and gamma without deterior ating the FOM in magnetic fields up to 5 mT.\nIt has been demonstrated tha t a new scintillation detector with a magnetic shield effectively detects fast neutrons in gamma background at the HELIS accelerator facility.\n\nht tps://indico.particle.mephi.ru/event/35/contributions/2223/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2223/ END:VEVENT BEGIN:VEVENT SUMMARY:Chemical freeze-out of light nuclei in high energy nuclear collisi ons and resolution of the hyper-triton chemical freeze-out puzzle DTSTART;VALUE=DATE-TIME:20201008T080000Z DTEND;VALUE=DATE-TIME:20201008T081500Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2351@cern.ch DESCRIPTION:Speakers: Kyrill BUGAEV (Bogolyubov Institute for Theoretical Physics\, Kiev\, Ukraine)\nA new strategy [1] to analyze the chemical free ze-out of light (anti-\,hyper-)nuclei produced in high energy collisions of heavy atomic nuclei within an advanced formulation of the hadron resona nce gas model will be presented. This strategy is based on two different\, but complementary approaches to model the hard-core repulsion between th e light (anti-\,hyper-)nuclei and hadrons. The first approach uses an appr oximate treatment of the equivalent hard-core radius of a roomy nuclear cl uster and pions\, while the second approach is rigorously derived recently in [1] using a self-consistent treatment of classical excluded volumes of light (anti-\,hyper-)nuclei and hadrons. By construction\, in a hadron ic medium dominated by pions\, both approaches should give the same resul ts. Applying this strategy to the analysis of hadronic and light (anti-\, hyper-)nuclei multiplicities measured by ALICE at \n$\\sqrt{s_{NN}} =2. 76$ TeV and by STAR at $\\sqrt{s_{NN}} =200$ GeV it was possible to avoid the existing ambiguity in the description of light (anti-\,hyper-)nucl ei data and to determine the chemical freeze-out parameters of such nuc lei with very high accuracy and confidence. \n\nUsing this strategy it was also possible to resolve a long standing problem to describe the light (a nti-\,hyper-)nuclei multiplicities including the hyper-triton measured by the STAR Collaboration\, known as the hyper-triton chemical freeze-out pu zzle [2]. Its solution was found by employing the hard-core radius of the (anti-)$\\Lambda$ hyperons which was found in our earlier works. One of t he most striking results of our analysis made in [2] is that for the most probable scenario of chemical freeze-out at the STAR energy \nof collision s the obtained parameters allow to simultaneously reproduce the values of the experimental ratios $S_3$ and $\\overline{S}_3$ which were not includ ed in the fit.

It is possible to study the p roduction of protons in nucleus-nucleus collisions\, including by measurin g the factors of nuclear modification ($R_{AB}$). Previously $R_{AB}$ for protons were measured in symmetric Au+Au collisions at $\\sqrt{s_{NN}}$ =   200 GeV. Comparison of Au+Au results with asymmetric Cu+Au system allo ws to study the influence of collision geometry on proton production.  I n order to investigate influence of quark content on production of protons consisting of three quarks comparison with $\\varphi$\, $\\pi^{0}$-mesons (quark antiquark pairs) was provided in Cu+Au and Au+Au collisions at the collision energy of 200 GeV. Such information can improve our understand ing of quark-gluon plasma and recombination model.\nThe results of the res earch concluded that for Cu+Au and Au+Au collisions $R_{AB}$ values for protons are consistent at similar number of participants. It seems that p roton production scales with the average size of the nuclear overlap regio n and do not depends on the details of its shape. For the most central Cu+ Au collisions proton yields are enhanced ($R_{AB}$ > 1) at $p_T$ > 2 GeV /c\, while $\\pi^{0}$ and $\\varphi$-mesons yields are suppressed. Obs erved difference in $R_{AB}$ values for protons\, $\\varphi$ and $\\pi^{0 }$-mesons disappears from central to peripheral collisions.\n\nhttps://in dico.particle.mephi.ru/event/35/contributions/2359/ LOCATION:Zoom Heavy Ion URL:https://indico.particle.mephi.ru/event/35/contributions/2359/ END:VEVENT BEGIN:VEVENT SUMMARY:Forward scintillator and quartz hodoscopes for BM@N experiment DTSTART;VALUE=DATE-TIME:20201005T143000Z DTEND;VALUE=DATE-TIME:20201005T170000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2228@cern.ch DESCRIPTION:Speakers: Александр Баранов ()\nAt present\, t he BM@N experimental setup is prepared for the next stage of operation wit h light and heavy ion beams.

A new multi-stage technology is developed and tested at NRNU MEPhI for proce ssing liquid xenon working medium in order to achieve more than 10 ms quas i-free electron lifetime before capture by electronegative impurities.\n\n The processing consists of a few stages. In the first stage\, liquid xenon is irradiated by the hard ultraviolet radiation generated by an electric high-voltage discharge in a liquid\, for the purpose of decomposition of c omplex high-molecular impurities due to photolysis. At the second stage\, a massive sample of liquid xenon is purified with nanodispersed titanium g etter generated in the liquid by a high-voltage electric discharge between the titanium electrodes. At the third stage\, which can run parallel to t he first and second stages in time\, the internal surfaces of the detector and gas communication lines are cleaned by repeatedly circulating the gas eous xenon through a hot metal getter in a closed loop. At the fourth stag e\, already during the operation of the detector\, the liquid xenon is wit hdrawed from the filled detector\, evaporated in a special heat exchanger\ , goes through the hot metal getter\, and condensates into the detector by means of a heat exchanger. This stage is carried out simultaneously with a physical experiment and assumes a continuous measurement of the lifetime of electrons before capture by electronegative impurities to correct the experimental data obtained.\n\nThe developed multi-step technology has bee n demonstrated to be an effective method for obtaining necessary (satisfyi ng highest experimental requirements) purity of raw xenon material contami nated during a previous isotope modification process.\n\nhttps://indico.pa rticle.mephi.ru/event/35/contributions/2231/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2231/ END:VEVENT BEGIN:VEVENT SUMMARY:Development of Si Beam Position Detectors for NA61/SHINE experimen t DTSTART;VALUE=DATE-TIME:20201005T143000Z DTEND;VALUE=DATE-TIME:20201005T170000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2232@cern.ch DESCRIPTION:Speakers: Aleksandr Makhnev (INR of RAS)\nThe NA61/SHINE detec tor at the CERN SPS is undergoing a major upgrade during the LHC Long Shut down 2 period (2019-2021).

A better understanding of the flux and neutrino-nucleus inter actions models are indeed essential to determine the neutrino mass hierarc hy and the extent of CP-violation generated in the lepton sector. In parti cular\, one of the main challenges in achieving such precision stems from the absence of knowlegde of nuclear physics processes that obfuscate the r econstruction of neutrino energy and therefore the characterisation of neu trino oscillations. To overcome these difficulties\, the upgraded detector will feature lower threshold for proton reconstruction\, measurement of n eutrons through time of flight and increased phase space of track reconstr uction at high and backward angles. Thanks to these new capabilities\, the upgrade of ND280 will be able to measure the neutrino energy spectrum to an unprecedented level of accuracy\, and thus guarantee the reliability of the near-to-far detector extrapolation of systematics constrains. In addi tion\, the measurement of neutrons will allow to select interactions of an tineutrino on hydrogen\, providing thus a very clean sample\; absent of nu clear physics uncertainties\; to measure the rate and energy distribution of the neutrino flux.\n\nAfter a brief overview of the status of such unce rtainties in the latest T2K analysis\, the physics program of ND280 upgrad e will be introduced by demonstrating how the expected detector performanc e will allow us to probe the aspects of neutrino interactions responsible for the largest systematics in T2K's neutrino oscillation analyses. We fur ther show the results of a simplified sensitivity analysis were the simula tion of the detector effects is benchmarked by present data collected at T 2K and in various test-beam prototypes.

The first one is a duality between the chir al symmetry breaking and the charged pion condensation\nphenomena. And the re are two other dualities that hold only for chiral symmetry breaking and charged pion condensation phenomena separately. For example\, we have sho wn that charged pion\ncondensation does not feel the difference between ch iral and isospin imbalances of the medium. They were shown to exist in the matter with chiral imbalance that can be produced in compact stars or hea vy\nion collisions. One of the key conclusions of these studies is the fac t that chiral imbalance generates charged pion\ncondensation in dense bary onic/quark matter. It was shown that our results in particular cases are c onsistent with the simulation of lattice QCD\, which is possible in these cases.\nDuality was used to show that there takes place catalysis of chira l symmetry breaking by chiral imbalance.\nIt was also shown that chiral im balance generates the phenomenon of charged pion condensation in dense bar yonic/quark matter even in the case of charge neutral matter\, which is in teresting in the context of the astrophysics of neutron stars.\nIt is know n that chiral imbalance can occur in high energy experiments of the collis ion of heavy ions\, due to\ntemperature and sphaleron transitions. Our stu dies show that different types of chiral imbalance can occur in the cores of neutron stars or in heavy ion experiments\, where large baryon densitie s can be reached\, due to another phenomena - the so-called chiral separat ion and chiral vortical effects.\nDuality was shown to exist even in case of inhomogeneous condensates. This example shows that the duality is not j ust entertaining mathematical property but an instrument with very high pr edictivity power.\nThe unified picture and full phase diagram of isospin i mbalanced dense quark matter have been assembled. Acting on this diagram b y a dual transformation\, we obtained\, in the framework of an approach wi th spatially inhomogeneous condensates and without any calculations\, a fu ll phase diagram of chirally asymmetric dense medium.\n\nContinuing our st udies of dualitiesl\, we noted that there are dualities in 2-color QCD tha t are connected with adiitional symmetry of QCD with two colors namely Pau li-Gursey symmetry.\nIt has been also shown that found duality is a more f undamental and can be shown at the level of Lagrangian. It has been shown that duality is a property of real QCD. It is not bounded by large Nc appr oximation and exists in the cases of 2 and 3 and infinite number of colour s.\n\nPart of the talk is\nbased on:\nPhys.Rev. D95 (2017) no.10\, 105010\ nPhys.Rev.

The original idea of this work\nis to extract\, in various time windows\, the average energy\nd ensity\, the net baryon density and the small though nonzero net\nstrangen ess density. By fitting these parameters to statistical model\,\nwe obtain temperature and chemical potentials of baryon charge\nand strangeness.

One of t he most important problem for that type of detectors is separating point-l ike events with 2-6 emission electrons (CEvNS) from background events. Thi s work is about modelling CEvNS and background events and applying ML and other methods for separating them.

Using the Wigner formulation of quantum mechanics we show the equivalence of the quantum-mechanical and kinetic approaches in the l imit of collisionless neutrino propagation (in a background medium). We al so argue that solutions of the kinetic equation account for the Heisenberg uncertainty principle and the related effect of wave packet separation (f or single neutrinos)\, as well as the Pauli exclusion principle\, if the i nitial conditions are consistent with these fundamental quantum principles . Such initial conditions can be constructed e.g. by identifying the matri x of densities with the (reduced) single-particle Wigner function computed using initial conditions for the neutrino wave function.

The improvement of this value relies on the increase of statist ics as well as a major reduction of reactor and detection systematics than ks to the iso-flux configuration and a novel detection technique\, called "Total neutron Capture". This new method enhances neutrino detection by ex ploiting the neutron captures on all available nuclei (Gd-n\, H-n C-n) res ulting in the increase of the detection volume by the factor of 3 and redu ction of some major systematics. The main analysis carried out to perform the latest measurements will be presented\, as detailed in latest publicat ion in Nature Physics 2020: “First Double Chooz Measurement via Total N eutron Capture Detection”\n\nhttps://indico.particle.mephi.ru/event/35/c ontributions/2260/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2260/ END:VEVENT BEGIN:VEVENT SUMMARY:On stable exponential cosmological solutions with three different Hubble-like parameters in EGB model with a Λ-term DTSTART;VALUE=DATE-TIME:20201006T092000Z DTEND;VALUE=DATE-TIME:20201006T094000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2110@cern.ch DESCRIPTION:Speakers: Vladimir Ivashchuk ()\nWe consider a $D$-dimensional Einstein-Gauss-Bonnet model with a cosmological term $\\Lambda$ and two non-zero\nconstants: $\\alpha_1$ and $\\alpha_2$.

Leaving apart of possible mechanisms of the spin-2 space-time perturbations production\, we will consider the cas e of their subsequent propagation with possible scattering on another blac k holes. Specifically\, we consider a generalization of the Regge-Wheeler equation for the case of distorted black holes (black holes in surrounded matter) in Minkowski and AdS spaces\, the metric potential of which obeys the Liouville equation (T. Moskalets & A.J. Nurmagambetov Eur. Phys. J. C 55 (2015) 551). The absorption cross-section is computed for spin-2 parti cles (the axial perturbations over the background metric) in the small bla ck hole and long-wave approximations. The subsequent analysis of the probl em results in finding the natural restriction for the maximum angular mome ntum of the scattering/absorbed waves and in establishing the spectrum of the absorbed frequencies in AdS$_{4}$ space. In sum up we find a good agre ement of the established results with the early obtained (A.A. Starobinski & S.M. Churilov Sov. Phys.

We consider a scalar black hole as a simple mode l of supermassive black holes in the centers of galaxies surrounded by dar k matter. Both the radius of the innermost stable circular orbit and the e vent horizon radius of such an object are less than those of a Schwarzschi ld black hole with the same mass. Moreover\, they can be arbitrary small\, so that tidal forces\, acting on a star orbiting a scalar field black hol e near its horizon\, can be sufficiently large to disrupt the star. This m eans\, in turn\, that tidal effects can play an important role for the int erpretation of observations in galactic astrophysics.\n\nhttps://indico.pa rticle.mephi.ru/event/35/contributions/2114/ LOCATION:Zoom URL:https://indico.particle.mephi.ru/event/35/contributions/2114/ END:VEVENT BEGIN:VEVENT SUMMARY:Search for periodic varioations of nucleus weak decay parameters DTSTART;VALUE=DATE-TIME:20201008T153500Z DTEND;VALUE=DATE-TIME:20201008T155000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2264@cern.ch DESCRIPTION:Speakers: Sergey Mayburov (Lebedev institute of Physics)\nPoss ible temporal variations of nucleus decay parameters studied extensively in the last years\, their observation can be the signal of unknown phy sical effects. Earlier\, several experiments reported the annual and daily decay rate oscillations in alpha and beta-decays of some nuclides of the order .05 % [1\,2]. Also\, correlation of Mn-54 weak decay rate with Su n activity\, in particular\, with solar flares was reported\, which can ha ve important practical applications [1]. BSTU - PhIAN collaboration studi es the decay rate variations in inverse beta-decay (e-capture) of Fe-55 i sotope in Moscow lab.. In this process K-shell electron absorbed by nuclei and electron neutrino emitted\; it accompanied by X-ray with energy 5\,9 or 6\,4 KeV which in our set-up detected by cooled Si-Pin detectors. Measu rements of decay rate performed in 2016 -2019 \, demonstrate that together with observed Fe-55 decay exponent with life-time 1004 days\, annual osc illation component value is present at the level (.11 +/- .02)%. Another p eriod 29.5 +/- 1.5 days corresponding to moon month is found with amplitud e (.22 +/- .04)% . \n Possible influence of electromagnetic Sun a ctivity was studied during\n 2017 – 2019 for Fe-55 decay rate\, simultan eously with Co-60\, Cs-137 beta-decay rate\nmeasured by germanium detecto r in Novosibirsk INF at the distance 2800 km from Moscow. \n The deviation s of similar form and size from exponential decay low at the average leve l\n (.55 +/-.004)% were detected in both experiments during October- Decem ber 2018 .

Applications of the logarithmic fluids can also be found in a theory of physical vacuum\, which is a popular framework for explaining a phenomenon of gravity. Using the logarithmic superfluid model\, one can formulate quantum post-relativistic theory of superfluid vacuum\, which me rges with special and general relativity in the “phononic” (low-moment a) limit\, but differs at higher momenta [4-9]. \n\nHere we derive an effe ctive gravitational potential induced by the quantum wavefunction of physi cal vacuum in a stationary state\, while the vacuum itself is viewed as th e superfluid described by the logarithmic quantum wave equation. We determ ine that gravity has a multiple-scale pattern\, to the extent that one can distinguish sub-Newtonian\, Newtonian\, galactic\, metagalactic and cosmo logical terms. The last of these dominates at the largest length scale of the model\, where superfluid vacuum induces an asymptotically Friedmann– Lemaitre–Robertson–Walker-type spacetime\, which provides an explanati on for the accelerating expansion of the Universe. Under certain condition s\, the model predicts an occurrence of two expansion mechanisms\, which c ould explain the discrepancy between measurements of the Hubble constant u sing different methods. On a galactic scale\, our model explains the non-K eplerian behaviour of galactic rotation curves\, as well as why their prof iles can vary depending on the galaxy. It also makes a number of predictio ns about the behaviour of gravity at larger galactic and extragalactic sca les\, which are expected to be seen in the outer regions of large spiral g alaxies [10].\n\n**References**:\n\n[1] K.G.

The main motivation for the study is the prospect of using these unst able states in the search for more complex unstable states that decay with their participation. The possibilities of the NTE method for studying the contribution of multiple ensembles of the lightest He and He nuclei to th e fragmentation of relativistic nuclei are presented described in brief. I t is shown that to identify relativistic decays 8Be and 9B and HS in NTE\, it is sufficient to determine the invariant mass as a function of angles in pairs and triples of He and H fragments in the approximation of conserv ation of momentum per nucleon of the parent nucleus. The formation of HS i n the dissociation 16O → 4α is observed. According to the criteria esta blished in this way\, the contribution of the unstable states to the relat ivistic fragmentation of 28Si and 197Au nuclei was estimated.

Strong increase o f number of relativistic electrons ensures an energetic terrestrial gamma- ray bursts (bremsstrahlung photons created at slowing down of relativistic electrons)\, that leds to (g\,n)-reactions on atmospheric isotopes: so\, the cross section 14N(g\,n)13N (with Ethreshold ~10.6 MeV) – within the interval (1-10) mb for Eg =20-60 MeV. By-turn neutron flux leads to gener ation of radiocarbon 14N(n\,p)14C\, 40Ar(n\,g)41Ar\, 14N(n\,alpha)B11\, 14 N(n\,g)15N and another reactions [2\, 3].\nHere we evaluate creation of 14 C (exclusively important for radiochronology) the under conditions of ter restrial flashes. The simulation were realized at the several altitudes: 1 \, 3\, 5\, 7 and 10 km. Change of atmospheric density was taken into calcu lation. We propose the top level of 14C production in the atmospheric flas hes as ~2 moles per year. This evaluation is connected only with flashes i n the lower part of the atmosphere at the altitudes up to ~ 15 km. \nAt th e same assumption it was obtained the rate of radioactive 41Ar production as ~4E-3 moles per year. We propose to use creation of 41Ar under conditio n of terrestrial flashes as sensitive tracer of radiocarbon production und er thunderstorms. The control engineering of radioactive 41Ar is well know n and continually fixed at accelerator work. \n\n1. Dwyer\, J. R.\, M. A. Uman\, and H. K.

Further\, by clubbing the $\\eta N$ equation of motion with the scalar density\, the in-medium mass and optical potential of $\\ eta$ meson is derived. The asymmetric matter affects are introduced throug h the scalar-isovector field $\\delta$ and the vector-isovector field $\\r ho$. We find attractive mass-shift of the $\\eta$ meson which becomes more attractive with the increase in density. The negative mass-shift indicate s the possibility of the formation of $\\eta$-mesic nuclei.\n\nhttps://ind ico.particle.mephi.ru/event/35/contributions/2362/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2362/ END:VEVENT BEGIN:VEVENT SUMMARY:Search for halo in isobar-analog states DTSTART;VALUE=DATE-TIME:20201008T090000Z DTEND;VALUE=DATE-TIME:20201008T091500Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2271@cern.ch DESCRIPTION:Speakers: Alla Demyanova ()\nOne of the most striking discover ies in nuclear physics made at the end of the past century was the finding the neutron halo in the ground states of some light nuclei located near t he neutron stability boundary. The halo manifests itself in the presence o f a diffuse surface region surrounding a core with a normal nuclear densit y and containing only neutrons. The result is a long "tail" of their wave function and\, correspondingly\, an increase in the radius of the entire n ucleus in a given state.\n\nThe discovery of the halo led to a revision of many existing ideas in nuclear physics. The purpose of our research is to search and study halo in isobar - analog states of light nuclei. The stud y of states with a halo in isobar analogs allows one to investigate the ma nifestation of isotopic invariance at new objects and to relate the proper ties of the neutron and proton halo. Of particular interest is the accumul ation of information that states possessing halo properties can be located not only in the discrete spectrum\, but also in the continuum\, and the p roblem of their unified description is formulated as one of the most impor tant The question of the existence of halo in isobar - analog states has s o far not been practically raised in the experimental plan.\nOur approach is based on measuring the radii of states in which the halo exists or can exist. Its first application made it possible to determine the proton halo in an unbound state of $^{13}$N. \n\nThe first object we started was the triplet A=12. Radii of the states of the isobaric triplet $^{12}$B-$^{12}$ C-$^{12}$N were determined using two methods asymptotic normalization coef ficients (ANC) and modified diffraction method (MDM). We obtained that the 1- excited states at E$_x$ = 2.62\, 17.23\, and 1.80 MeV\, respectively\, possess one-nucleon (neutron or proton) halo structure. The enlarged radi i and large values of D$_1$ coefficient are also found for the 2$^-$ state s of $^{12}$B\, $^{12}$C\, and $^{12}$N at E$_x$ = 1.67\, 16.57 and 1.19 M eV\, respectively. These IASs also can be regarded as candidates to the st ates with one-nucleon (neutron or proton) halo.\n\nThe second object was t riplet A=14. Signs of neutron halo in the 1$^{-}$ (6.09 MeV) state of $^{1 4}$C have been revealed earlier by two independent groups. We confirmed th is result independently and studied isobaric analog 1$^{-}$ states of neig hboring $^{14}$N and $^{14}$O nuclei. The differential cross sections of t he $^{14}$C($\\alpha$\,$\\alpha$)$^{14}$C$^*$ (6.09 MeV\, 1$^{-}$) inelas tic scattering\, the $^{13}$C($^{3}$He\,d)$^{14}$N$^*$ (8.06 MeV\, 1$^{-}$ )\, and the $^{14}$N($^{3}$He\,t)$^{14}$O$^*$ (5.17 MeV\, 1$^{-}$) reactio ns are analyzed by the MDM and ANC. The rms radii for all three mirror nuc lei in the studied 1$^-$ states are found almost the same. The signs of pr oton halo in the 1$^-$ state of $^{14}$N are identified for the first time .\n\nOur future plans are connected with the radii of states of the $^6$Li and $^6$Be nuclei members of the $^6$He-$^6$Li-$^6$Be isobaric triplet. T he formation of a neutron-proton halo in the $^6$Li state (3.56 MeV\, 0$^+ $) was predicted. The theory admits the existence in this state of the so- called "tango structure". A proton or two-proton halo is expected in the g round state of $^6$Be. The radii of the above states will be determined by inelastic scattering and the ($^3$He\,t) reaction using MDM.\n\nhttps://i ndico.particle.mephi.ru/event/35/contributions/2271/ LOCATION:Zoom Nuclear URL:https://indico.particle.mephi.ru/event/35/contributions/2271/ END:VEVENT BEGIN:VEVENT SUMMARY:Observation of the excited states from the 9Be(d\,d)9Be reaction DTSTART;VALUE=DATE-TIME:20201005T164500Z DTEND;VALUE=DATE-TIME:20201005T170000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2272@cern.ch DESCRIPTION:Speakers: Viktar Starastsin (NRC Kurchatov Institute)\nThe exp eriment was conducted at the HI-13 tandem accelerator at the China Institu te of Atomic Energy (CIAE) in Beijing.

TileCal is a sampling calorimeter composed of plast ic scintillators interleaved by iron plates. Wavelength shifting optical f ibres collect the scintillating light from the tiles and are read by photo multiplier tubes (PMTs). The calorimeter comprises 64 wedged modules acros s the azimuthal direction\, segmented radially and in pseudorapidity to de fine the 5000 detector cells. Double cell readout\, by approximately 10000 PMTs\, provides redundancy in the cell energy measurement. \nTh e TileCal energy scale was determined a priori with test beam measurements and\, during operation\, dedicated calibration systems allow to monitor e ach step of the readout chain independently to address respective response fluctuations. A Cesium radioactive source assesses the response of the wh ole detector\, a laser system provides controlled light pulses to monitor the photodetectors and the front-end electronics is calibrated through cha rge injection. Besides\, the integrated current of the cells' response to minimum bias events provides auxiliary information on the whole detector r esponse stability during proton collisions. \nThe performance of the detector during Run 2 was studied with cosmic ray muons and the large sample of proton-proton collisions during data qu ality assessment activities. Furthermore\, isolated hadrons and high momen tum muons were used as probes to study the response of the calorimeter at the hadronic and electromagnetic energy scale\, respectively. The influenc e of pile-up on the detector noise levels and the detector response unifor mity were also analysed and compared to estimates from Monte Carlo simulat ion. Finally\, the time resolution of TileCal was investigated with multij et events. \nIn this pr esentation\, the methods and results of the TileCal Calibration and Perfor mance during Run 2 will be presented.\n\nhttps://indico.particle.mephi.ru/ event/35/contributions/2282/ LOCATION:Zoom Facilities URL:https://indico.particle.mephi.ru/event/35/contributions/2282/ END:VEVENT BEGIN:VEVENT SUMMARY:Particle configurations in $NN\\bar K$ quasi-bound state DTSTART;VALUE=DATE-TIME:20201005T164500Z DTEND;VALUE=DATE-TIME:20201005T170000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2275@cern.ch DESCRIPTION:Speakers: Igor Filikhin (North Carolina Central University)\nT hree-body $NN\\bar K$ model for the "$ppK^-$" quasi-bound kaonic cluster i s considered on the basis of the configuration space Faddeev equations.

Due to their large masses\, heavy quarks are produced almost exclusively in initial hard part onic scatterings and survive up to the later stages of the collision. Unex pected collective-like behaviours of heavy and light flavour particles hav e been observed in small systems\, in events with high final state multipl icity\, that are similar to collectivity in heavy-ion collisions where the quark-gluon plasma (QGP) is formed. Recent studies attribute this behavio ur to semi-hard vacuum QCD effects such as of Multiple-Parton Interactions (MPI).\n\nIn this talk\, we will present recent ALICE results of inclusiv e and multiplicity dependent production of heavy-flavour particles in pp c ollisions. Besides providing a reference for nuclear modification of heavy -ion collisions\, these results give insight into the semi-hard QCD effect s mentioned above.\n\nhttps://indico.particle.mephi.ru/event/35/contributi ons/2368/ LOCATION:Zoom Heavy Ion URL:https://indico.particle.mephi.ru/event/35/contributions/2368/ END:VEVENT BEGIN:VEVENT SUMMARY:Partial-wave analysis of $J/\\psi\\to K^+K^-\\pi^0$ DTSTART;VALUE=DATE-TIME:20201007T100000Z DTEND;VALUE=DATE-TIME:20201007T101500Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2369@cern.ch DESCRIPTION:Speakers: Igor Denisenko (JINR)\nThe recent results of the par tial wave analysis of $J/\\psi \\to\nK^+K^-\\pi^0$ reaction using $(223.7\ \pm1.4)\\times 10^{6}$ $J/\\psi$ decays collected by BESIII collaboration in 2009 will be presented.

One of the experimental observables is the anisotropic flow $v_n$\, defined as correlation of azimuthal angle of each particle with respect t o a common symmetry plane $\\Psi_n$. The $v_n$ and $\\Psi_n$ represent the magnitude and the phase of a complex flow vector $V_n$\, respectively. Az imuthal anisotropies are traditionally measured using 2- and/or multi-part icle correlations over a large range in $p_\\mathrm{T}$ and $\\eta$. Howev er\, hydrodynamic calculations show that the event-by-event fluctuations i n the initial conditions and the dynamics during the system expansion lead to flow vector fluctuation in $p_\\mathrm{T}$ and/or $\\eta$ (also called de-correlations of flow vector)\, including flow magnitude and flow angle fluctuations.\\\\\nIn this talk\, we present the evidence of $p_{\\rm T}$ -dependent flow vector fluctuations in Pb--Pb collisions at $\\sqrt{s_{_{\ \rm NN}}}=5.02$ TeV\, using both $v_{n}\\{2\\}/v_n[2]$ and $r_{n}$ observa bles. In addition\, newly proposed four-particle correlations are used to study the contributions of flow magnitude and flow angle fluctuations sepa rately. Considering that the size of flow vector fluctuations is sensitive to both initial conditions and the properties of the created QGP\, these measurements will help us better constrain hydrodynamic models.\n\nhttps:/ /indico.particle.mephi.ru/event/35/contributions/2346/ LOCATION:Zoom Heavy Ion URL:https://indico.particle.mephi.ru/event/35/contributions/2346/ END:VEVENT BEGIN:VEVENT SUMMARY:Recent CMS results on exotic hadron states DTSTART;VALUE=DATE-TIME:20201007T091000Z DTEND;VALUE=DATE-TIME:20201007T093000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2372@cern.ch DESCRIPTION:Speakers: Ivan Lilienberg (Moscow Institute of Physics and Tec hnology)\nRecent CMS results on exotic states\, including X(3872) and sear ch for new states decaying into Y(1S)mu+mu-\, are presented.

This phenomenon is not fully understood. Nowadays\, most of the data is obtaining using satellites on low orbits. However\, breakdown can also occur at altitudes of less than 30 km. In this case\, most of the ra diation is scattered without reaching the satellites on high orbits. The f ormation of charged particles in the atmosphere can affect the results of other experiments. It is important to have the most proper model of this p henomenon.

As a rule\, these are modules based on a large number of PMTs in quasispherical configuration which allows getting the response practically independent on Cherenkov light direction. In this regard\, it becomes necessary to develop new methods for testing of optical modules in an environment as close as possible to the working conditions inside the neutrino telescopes. \n For the calibration of OMs\, usually LED or las er sources with fixed wavelengths are used. They cannot imitate the contin uous spectrum and the directionality of the Cherenkov radiation sufficient ly well. Therefore the calibration of these OMs in a Cherenkov water detec tor is advantageous. NEVOD is presently worldwide the only setup which mee ts these requirements.\n The possibility to calibrate new optical modul es mDOM of the IceCube-Upgrade neutrino telescope inside the tank of the C herenkov water detector NEVOD is discussed.

These bricks function is to step-down bulk 200VDC current to the 10VDC current r equired by the front-end electronics of a TileCAL module. Due to the LVPS bricks being located on-detector they are of a highly refined custom desig n. Within the development and production phase of these bricks the use of a custom built test-bed known as the Burn-in station is required. The Burn -in test station functions to detect the premature failure of electronic c omponents on an LVPS brick via a process known as accelerated ageing.

A high penetrating ability makes muons an a ttractive tool for muonography [1]. Muonography is the method\, for the de velopment of which muon hodoscopes TEMP and URAGAN were first created in M EPhI [2]. \nThe task of this work is to create a model of a new scintillat ion muon hodoscope for the development of the method of muonography of lar ge-sized objects. The model is based on a scintillation detector [3]. The registration of muon tracks is carried out by several layers of narrow lon g scintillation strips with fiber-optic light collection on silicon photom ultipliers. The model of future scintillation muon hodoscope strip was cre ated in the Geant4 program package [4]\, and all necessary optical propert ies were included. Then the model of a muon hodoscope consisting of four c oordinate planes was created. Each coordinate plane consists of two layers (128 strips each) with mutually perpendicular strips. The strip model was calibrated according to experimental data\, and more exact parameters of muon hodoscope model were obtained from calibration results. For simulatio n of muon hodoscope response to cosmic-ray particles passing through it\, in order to obtain dependences most consistent with the experiment\, the s pectrum of cosmic-ray particles was simulated\, which is close to a real o ne [5]. The tracks of muons were reconstructed [6] and accuracy of their r econstruction was estimated. The obtained distributions of events in the a ngle between reconstructed and “real” tracks for various detector para meters and selection of optimal parameters to achieve a highest accuracy a nd efficiency of reconstruction of muon tracks are discussed.\nThe work wa s performed at the Unique Scientific Facility "Experimental complex NEVOD" .\n\nReferences\n\n1.

Using this technology\, within the framework of the NICA / MPD project\, a cylindrical electromagnetic calorimeter (ECAL) with a di ameter of 4 m and a length of 6 m is being created. It contains 38400 towe rs of the "shashlyk" type with a total weight of about 60 tons. The towers represent a truncated pyramid with a base of 4x4 cm2\, containing 200 alt ernating 1.5 mm thick polystyrene scintillator and 0.3 mm thick lead plat es pierced with 16 Kuraray Y11 wavelength shifting (WLS) fibers 1.2 mm in diameter for collecting light on an avalanche silicon multipixel photon co unter (MPPC) Hamamatsu S13360-6025PE (~ 64000 cells) with an area of 6x6 m m2. In this configuration\, one can hope to obtain subnanosecond time reso lution for ECAL towers. This will expand the capabilities of ECAL in parti cle identification\, background rejection and clustering in high multiplic ity events. .This report is devoted to modeling the time response of ECAL. In full\, this task is reduced to obtaining the distribution of energy re lease in scintillators\, converting it into blue light\, collecting these photons on the WLS fibers\, converting blue to green light and capture i t in fibers\, transportation to the MPPC\, shaping its output signal and r egistration by digital electronics.

Rare semileptonic decays of $B$-mesons\, originating by these currents\, are extremely useful tools for testing the Standard Model and s earching for a possible physics beyond the Standard Model. Differential br anching fractions of semileptonic $B$-decays and angular distributions in some of them are experimentally measured by LHCb\, ATLAS and CMS collabora tions at LHC as well as by BaBar and Belle at $B$-factories. Here\, we con sider the rare $B^+ \\to P \\ell^+ \\ell^-$ decay\, where $P$ is a pseudo scalar meson and $\\ell = e\, \\mu$ is a charged lepton. For example\, we present results on the dilepton invariant-mass spectrum and decay rate for $B^+ \\to \\pi^+ \\ell^+ \\ell^-$ based on the effective Hamiltonian appr oach for the $b \\to d \\ell^+ \\ell^-$ transitions in two cases — with taking into account weak annihilation diagrams and without this contributi on.

The cross sections for the production of top-quark pairs in association to a photon (ttgamma) or to a Z boson (ttZ) are measured both inclusively and differentially as a f unction of kinematic variables characterizing the tt+boson system. Both se ts of measurements use the full Run-2 data set corresponding to 139/fb of integrated luminosity. Final states with three and four leptons and b-jets are used to extract ttZ rates\, while tt+gamma cross sections are derived from final states with one photon\, one electron and one muon of opposite sign and at least two jets. The measurements are compared to predictions obtained by NLO+PS Monte Carlo generators and fixed-order NLO calculations .\nBased on a recent analysis the ATLAS collaboration established first ev idence for the hard scattering process in which two top-quark-antiquark pa irs are produced. This process is also called four-top-quarks production a nd is predicted to have a small cross-section of 12 fb in the standard mod el. Candidate events are selected if a lepton pair with the same electric charge is present or if there are at least three leptons in the event. The background is mainly given by top-quark-antiquark production in associati on with a W boson and heavy-flavour jets. A multivariate discriminant is u sed to optimize the separation between signal and background events and en hance the sensitivity.\nRecent measurements involving B-meson decays spark ed renewed interest in testing lepton universality between tau and light l eptons because of observed deviations at the four-standard-deviation level . By selecting events with two opposite sign leptons (muon pairs and elect ron-muon pairs) and at least two b-tagged jets\, a highly pure sample of t op-quark pair decays is assembled and used to extract a large unbiased sam ple of W bosons decaying to leptons down to low transverse momenta. A fit to the two dimensional distribution for the transverse momentum and the tr ansverse impact parameter of the lepton is then used to differentiate betw een leptons originating directly from the W boson and those resulting from the W-boson-to-tau-lepton decay chain. This results into the most precise measurement of the ratio of the probability for an on-shell W-boson decay to tau to the probability for its decay to muon.\n\nhttps://indico.partic le.mephi.ru/event/35/contributions/2385/ LOCATION:Zoom HEP URL:https://indico.particle.mephi.ru/event/35/contributions/2385/ END:VEVENT BEGIN:VEVENT SUMMARY:The Belle II Experiment: Status and Prospects DTSTART;VALUE=DATE-TIME:20201006T150500Z DTEND;VALUE=DATE-TIME:20201006T152500Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2387@cern.ch DESCRIPTION:Speakers: Ida Marena Peruzzi (INFN\, LNF)\nThe Belle II experi ment at the SuperKEKB energy-asymmetric $e^+ e^-$ collider is a substantia l upgrade of the B factory facility at the Japanese KEK laboratory.

There a re searches for particles that make up dark matter. These include axions\, neutrinos\, WIMP particles. Gravitation is explained by the law of univer sal gravitation. Repulsion of particles is not clear. The nature of repuls ive forces is unclear. However\, the runoff of galaxies from the Universe and the resulting blue lakes were discovered.\nThe cosmological vacuum is represented as an environment in which there are both real and virtual par ticles. In contrast to attempts to represent dark energy and dark matter i n the form of individual particles\, followed by their search\, a streamin g model was chosen to analyze the behavior of matter and the dark energy. It contains flows of ordinary matter\, as well as flows in the form of dar k matter and in the form of dark energy\, both the movement of the field a nd the movement of the vacuum\, as types of movement of matter.\nThe gravi tation field sent to the vacuum by its source results in counter displacem ent of the vacuum.

It is based on scintillating PbWO4 crystals and is\ndedicated to the precise me asurements of spectra\, collective flow and\ncorrelations of thermal and p rompt direct photons\, and of neutral mesons\nin ultra-relativistic nuclea r collisions at LHC energies. PHOS\nparticipated in LHC Run 1 (2009-2013) and Run 2 (2015-2018)\, during which a large\namount of physical data were collected in pp\, p-Pb and Pb-Pb collisions.\n\nThe choice of active mate rial with small Molière radius allows PHOS to\noperate in a high-multipli city environment and to reconstruct neutral pions\nby two-photon decays up to very high transverse momenta ~60 GeV/c. In\norder to increase the ligh t yield of the crystals and reduce electronic noise\,\nPHOS is cooled down and kept at a constant temperature of -25^{\\circ} C.

Moreover\, $H = 145.5 km/s$ an d $g = GM/R^2$. The peaks are created by the populated areas of the tempor al slowdown of the absolute evolutionary expansion of the DDLES component. Thus\, the absolute evolutionary expansion of any DDLES component is\, in particular\, its transitions along the coordinate axes $(GM/R)/H^2$ and $ \\log(g)$ between these areas with its temporary localization in the latte r. In this regard\, the quantum gravitational effects are found along thes e coordinate axes. For any DDLES indexes $1$ and $2$ indicate its first an d second components\, respectively. It is found that the distributions of the DDLESes along the coordinate axis $\\log(g_1/g_2)$ has four peaks\, th e positions of which are defined by the step of 0.0305. The peaks are crea ted by the populated areas of the temporal coordinated relative evolutiona ry expansion of the first and second DDLES components. The same quantum gr avitational effects are also found along the axes $\\log((GM/R)_1/(GM/R)_2 )$ and $\\log(R_1/R_2)$. Thus\, in any DDLES the relative evolutionary exp ansion of its first and second components is\, in particular\, their trans itions along the coordinate axes $\\log(g_1/g_2)$\, $\\log((GM/R)_1/(GM/R) _2)$\, $\\log(R_1/R_2)$\, between these areas with their temporary locali zation in the latter. The symmetric separation of the populated area of th e temporal coordinated relative evolutionary expansion of the first and se cond DDLES components into three such areas is found at $(GM/R)_1/(GM/R)_2 = 1$. It follows that in any DDLES there are some quantum physical system s which create the quantum stepwise absolute and relative evolutionary exp ansions of the first and second DDLES components. A general gravitational mass of any DDLES and the gravitational masses of its two components are p roposed as these quantum physical systems.\n\nhttps://indico.particle.meph i.ru/event/35/contributions/2405/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2405/ END:VEVENT BEGIN:VEVENT SUMMARY:Stopping of protons in pA collisions at SPS and NICA energies in a nalytical hydrodynamic model and in SMASH event generator DTSTART;VALUE=DATE-TIME:20201008T091500Z DTEND;VALUE=DATE-TIME:20201008T093000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2422@cern.ch DESCRIPTION:Speakers: Vera Ermakova (St. Petersburg State University)\, Vl adislav Sandul (St. Petersburg State University)\nOur study is motivated b y the first experimental results on pion production and stopping obtained in pA collisions in E910 experiment at BNL [1]. The effect of stopping is the decelera-tion of an incident high energy proton traversing the target nucleus. It appears due to the energy losses relevant to the production o f secondary particles in the inelastic interactions with nucleons. The eff ect is related to the number of inelastic nucleon-nucleon scatterings ($N _{coll}$)\, suf-fered by the projectile\, and the last quantity was esti mated in [1] by the measurable number of so-called “grey” particles –products of the recoil nucleon shower induced by the incoming pro-ton. The multiplicity () of negatively charged pions ($\\pi^-$) as a function of $N_{grey}$ demonstrated some peculiarities\, in particular\, deviation from linear was observed for large values of $N_{grey}$ [1]. \n\nWe hav e proposed previously a hydrodynamic effective model of stopping based on the consid-eration of the nuclear matter as a liquid and by the introducti on of an effective stopping force acting on a proton [2]. With this force we obtain a differential equation that describes relativistic motion of a proton in a nucleus. Setting the final speed - the speed after which binar y collisions do not contribute to multiplicity - we calculate the length o f the proton's path in the nucleus. This path length cuts out a region\, i n the nucleus to which we apply the Glauber-like approach to ob-tain numbe r of binary collisions. We obtained in the framework of this model the dep endencies on the impact parameter for such quantities as pion multiplicity \, the number of binary nucleon-nucleon collisions and the correlation fun ction vs. $N_{grey}$. \n\nIn this report\, results on the correlation bet ween mean multiplicity and a number of grey nucle-ons are compared to the available experimental data on centrality dependence of stopping and $\ \pi^-$ production in p+Au and p+Cu collisions at a beam momentum of 18 Ge V/c [1]. The de-pendencies $N_{ch}(b)\, N_{bin}(b)\, N_{\\pi^-}(N_{grey})$ in the collisions of high energy pro-tons with gold and with cuprum nucle i are also considered using SMASH [3] event generator. A comparison of the MC simulations with analytical hydrodynamic model calculations is also pe r-formed and results are discussed in view of binary collision estimates n eeded for the future SPS and NICA experiments.\n\n[1] I.

The active material is made of plastic scintillating tiles\, and the light produced in the scintillators is tran smitted to the photomultiplier tubes by wavelength shifting fibres. During the High Luminosity LHC (HL-LHC) program\, the luminosity can reach a val ue seven times higher than the one that TileCal was designed for. Two crit ical points that affect the detector performance are the increased exposur e to radiation that will degrade the TileCal optics and natural ageing. Si nce the optical components of the TileCal cannot be replaced\, the radiati on hardness must be evaluated. The Laser and Cesium calibration systems ar e used to evaluate the robustness of the TileCal optical components. Takin g advantage of these systems it is possible to isolate the response of the tiles and fibres and evaluate the evolution of the yield light with the d ose. The results obtained during the Run 2 were extrapolated to the end of the HL-LHC phase\, indicating that around 50% of the TileCal cells will l ose up to 35% of the light yield response. These cells correspond to the l east exposed to radiation\, for the most exposed cells the loss of the lig ht yield is more pronounced. Nevertheless\, the extrapolation uncertainty is large\, more data needs to be explored to reach better precision and fi ner conclusions. This study constitutes an essential step for predicting t he calorimeter performance in future runs.\n\nhttps://indico.particle.meph i.ru/event/35/contributions/2312/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2312/ END:VEVENT BEGIN:VEVENT SUMMARY:Gravitational Lensing by a black hole in non-Riemannian spacetimes DTSTART;VALUE=DATE-TIME:20201005T164500Z DTEND;VALUE=DATE-TIME:20201005T170000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2401@cern.ch DESCRIPTION:Speakers: Saboura sadat Zamani (Golestan University\, Iran)\nO ne of the consequences of Einstein’s general theory of relativity is ben ding of light as it passes through a gravitational field and it has been o ne of the first and most important results of general relativity. Some of the most important applications of gravitational lensing in cosmology are to study the large-scale distribution of matter and dark matter in the uni verse and specifying the Hubble and other cosmological parameters. Besides \, we can use this phenomenon to study black holes. Examining the path of light in a very strong gravitational field of a black hole can provide a h uge amount of information about the geometry and characteristics of the su rrounding space.\n\nOn the other hand\, the path of light rays\, extent\, and shape of gravitational lensing\, are directly related to the type of b ackground geometry in which light is emitted. Since the theory of general relativity in very high energies and very strong gravitational fields is e xpected to be corrected\, researchers have been looking at the phenomenon of gravitational lensing in the context of alternative theories for genera l relativity to find out the needed corrections for the results of general relativity and These corrections are likely to be more significant in a v ery strong gravitational field of a black hole. \n\nAmong the various theo ries that have been proposed for correcting the gravity in high energies\, gauge theories of gravity have great importance. One of the important res ults of these theories is changing the geometry for the background in gene ral relativity\, Riemannian space-time\, to a kind of non-Riemannian geome try in which\, in addition to curvature\, there is also torsion. Such theo ries include the Einstein-Cartan-Sciama-Kibble theory\, Poincaré gauge th eory of gravity\, Teleparallel gravity and Conformal gauge theory of gravi ty (Weyl). In all of these theories\, the presence of torsion coupled to s pin of a matter can affect the path of light rays and correct the results of gravitational lensing.\n\nIn this work\, we want to study the effects o f non-Riemannian geometry on the gravitational lensing of a black hole\, a nd in particular the effects of torsion and spin in this context.\n\nhttps ://indico.particle.mephi.ru/event/35/contributions/2401/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2401/ END:VEVENT BEGIN:VEVENT SUMMARY:QUANTUM GRAVITATIONAL EFFECTS IN ROTATION OF BIG BODIES DTSTART;VALUE=DATE-TIME:20201005T164500Z DTEND;VALUE=DATE-TIME:20201005T170000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2404@cern.ch DESCRIPTION:Speakers: Sergei Sinitsyn ()\nIt is found that the distributio n of 254 detached double-lined eclipsing systems along the coordinate axis of the second degree of the relative orbital velocity of their first and second components has two peaks about $H^2$\, $2H^2$\, where $H = 145.5 km /s$. The distribution of 2195 spiral galaxies along the coordinate axis of the second degree of the "plateau" orbital velocity of galaxy stars has t hree peaks about $(1/2)H^2$\, $H^2$\, $2H^2$. Thus\, detached double-lined eclipsing systems and spiral galaxies rotate like the quantum hard rotato r. The planets of the Solar System rotate like the quantum Kepler rotator. For each of these planets\, the semi-major axis of the orbit $a$ is $(GM/ H^2)n^2$\, where $M$ is the mass of the Sun and $n$ is the number of the o rbit. For Mercury\, Venus\, Earth\, Mars\, Jupiter\, Saturn\, Uranus\, Nep tune and Pluto $n$ equals 3\, 4\, 5\, 6\, 11\, 15\, 21\, 27 and 31\, respe ctively. In this case\, the average difference between the calculated and empirical values of $a$ is $3.0\\%$ with the maximum value of $7.3\\%$ for Venus. From the analysis of the planet orbits of the Solar System it is d etermined that $(GM/H^2)n^2$ is valid when $Gm/n^2 \\geq 1190$ $km^3/s^2$\ , where $m$ is the planet mass. For the biggest bodies of the Solar System \, Jupiter and the Sun\, $(Gm/R)/H^2$ and $(GM/R)/H^2$ are 1/12 and 9 with an error of $0.4\\%$ and $0.08\\%$\, respectively. $R$ is the radius of a big body. In this regard\, it is proposed that with an increase in the ma ss of any big body $M$\, this body is compressed so that its reduced radiu s $R/GM$ decreases stepwise\, taking quantum values of $n(n + 1)/H^2$\, $n ^2/H^2$\, $1/H^2n^2$\, $1/H^2n(n + 1)$. Along the coordinate axis $M$\, th e lower boundary of the validity of this law is determined by Jupiter and Saturn. For stars\, the validity of the law depends on the energy release of nucleosynthesis. Existence of the law is found in stars less than 1.55 and more than 14.10 solar masses.\n\nhttps://indico.particle.mephi.ru/even t/35/contributions/2404/ LOCATION:Discord Poster Server URL:https://indico.particle.mephi.ru/event/35/contributions/2404/ END:VEVENT BEGIN:VEVENT SUMMARY:Second order hydrodynamics\, anisotropic expansion and holographic dual of QGP DTSTART;VALUE=DATE-TIME:20201006T082000Z DTEND;VALUE=DATE-TIME:20201006T084000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2121@cern.ch DESCRIPTION:Speakers: Priyanka Priyadarshini Pruseth (student)\nAdS/CFT co rrespondence has provided a very important tool for studying \nthe strongl y coupled dynamics in a class of superconformal field theories\, \nin part icular\, ${\\cal N} = 4$ super Yang-Mills theory \nand the corresponding gravity dual description in AdS space-time. \nIn this work\, we have used time dependent AdS/CFT correspondence to \nstudy the expansion of the str ongly coupled QGP (Quark-Gluon-Plasma) and \nthe corresponding gravity dua l desription. \nIn the context of the expanding plasma\, we have considere d non-isotropic \nexpansion in three dimensions which \nis a generalizatio n of Bjorken's one dimensional expansion.

These double layers describe the gravitational shock waves.\n\nhttps://i ndico.particle.mephi.ru/event/35/contributions/2117/ LOCATION:Zoom URL:https://indico.particle.mephi.ru/event/35/contributions/2117/ END:VEVENT BEGIN:VEVENT SUMMARY:Double polarisation observables G and E and helicity dependent cro ss section for single $\\pi^0$ photoproduction off proton and neutron at M AMI DTSTART;VALUE=DATE-TIME:20201008T081500Z DTEND;VALUE=DATE-TIME:20201008T083000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2270@cern.ch DESCRIPTION:Speakers: Susanna Costanza (University of Pavia)\nThe internal structure of the nucleon and the excitation spectra of protons and neutro ns have been a central issue for many theoretical models and experiments o f nuclear and particle physics since the beginning of the 1960's.\n\nUp to now\, most efforts have been devoted to studying proton excitation but\, since the electromagnetic excitations are isospin dependent\, also measure ments of meson-photoproduction off the neutron are required.\n\nThe A2@ MA MI collaboration is carrying out a broad and systematic study on these top ics\, both on the proton and the neutron. The experiments are performed at the tagged photon beam facility of the MAMI accelerator in Mainz\, using circularly and longitudinally polarized photons on longitudinally polarize d proton and deuteron targets\, for energies ranging from the pion product ion threshold up to 1.6 GeV. Hadronic reaction products are then measured with the large acceptance Crystal Ball spectrometer\, complemented by char ged particle and vertex detectors for tracking and identification.\n\nIn t his talk\, an overview of the results obtained so far for the double polar ization observables G and E on the single $\\pi^0$ photoproduction off the proton and the neutron will be given. \nNew results on the helicity-depen dence of the total inclusive photo-absorption $d\\sigma/d\\Omega$ cross se ctions for the $\\pi^0$ reaction channel on the proton and the deuteron w ill be presented.\nThese new\, high-quality doubly-polarized pion-photopro duction data sets give a valuable input to the study of the nucleon struct ure and excitation spectra of protons and neutrons\, by providing a contri bution to the partial wave analysis models and by allowing to constrain th e multipole solution of the different analyses.\n\nFurthermore\, the helic ity dependent observables provide the main ingredient for the verification of the well-known Gerasimov-Drell-Hearn (GDH) sum rule\, which relates th e helicity-dependent photoasborption process to the main static nucleon pr operties (mass\, charge\, spin). For this reason\, such a verification is of particular interest in the understanding of the nucleon spin structure\ , the $\\gamma -N$ interaction\, as well as the physics of strongly intera cting systems. Thanks to the use of polarized deuteron and $^3$He targets\ , the A2 experiment can study all the $\\gamma N \\rightarrow N\\pi(\\pi)$ partial channels and the total cross sections\, for the neutron too.\n\nM oreover\, the results obtained on $^3$He give information not only on the GDH integral on\nthe neutron\, but also on the $^3$He nuclear structure an d allow an investigation of the nucleon properties inside this nucleus.\n\ nhttps://indico.particle.mephi.ru/event/35/contributions/2270/ LOCATION:Zoom Nuclear URL:https://indico.particle.mephi.ru/event/35/contributions/2270/ END:VEVENT BEGIN:VEVENT SUMMARY:Equivalent photons approximation: survival factor DTSTART;VALUE=DATE-TIME:20201006T081500Z DTEND;VALUE=DATE-TIME:20201006T083000Z DTSTAMP;VALUE=DATE-TIME:20260606T140426Z UID:indico-contribution-35-2140@cern.ch DESCRIPTION:Speakers: Evgenii Zhemchugov (LPI\, MEPhI)\nIn a large fractio n of collisions at the Large Hadron Collider (LHC)\, the colliding particl es miss each other and collide with their electromagnetic fields. If the p articles remain intact after such collision\, the collision is called ultr aperipheral (UPC). In the equivalent photons approximation\, the electroma gnetic field of an ultrarelativistic particle can be represented as a bunc h of real photons distributed according to a known spectrum $n(\\omega)$. This allows treatment of UPCs as photon-photon collisions\, and the Large Hadron Collider as a photon-photon collider.

Calculations with and without the survival factor taken into accoun t are compared to the measurements of the cross section for muon pair prod uction in UPCs (low $s$). Effects of the survival factor on the production of heavy charged particles are discussed.

It is the main component of the EAS\, which forms the cha racteristics of the shower. Registration of neutrons produced in interacti ons of EAS hadrons with the environment is one of the new methods for stud ying EAS hadronic component. The URAN array was created in the Scientific and Educational Center NEVOD (MEPhI) in collaboration with INR RAS. The UR AN facility was designed to register neutrons that accompany EAS in the re gion of the primary cosmic ray spectrum break (‘knee region’). It incl udes 72 detectors based on a thin inorganic scintillator for registration of the charged and neutron components of the EAS. The total area of the fa cility is ~ 103 m2\; scintillation detectors are located on the roofs of t he laboratory buildings of the Unique Scientific Facility NEVOD. For the c orrect interpretation of the experimental data of the URAN\, the response of the URAN facility to the passage of EAS was simulated using the CORSIKA 7.6900 program and Geant4.10.5 software package. The report presents the r esults of studying the parameters of EAS registered by the URAN array in 2 019. It includes the LDF of charged particles\, the dependence of the numb er of neutrons on the parameters of EAS\, the EAS distribution in the numb er of neutrons. A comparison of the experimental data with model calculati ons is presented.\n\nhttps://indico.particle.mephi.ru/event/35/contributio ns/2199/ LOCATION:Zoom Astroparticle URL:https://indico.particle.mephi.ru/event/35/contributions/2199/ END:VEVENT END:VCALENDAR
