The tau neutrino interaction cross-section was only measured by the DONU T experiment in 2008 with a large systematical error of 50% due to a poor knowledge of the tau neutrino flux in this beam dump experiment. However\, the better measurement of this cross section is needed for the planned future neutrino experiments. It would also allow testing the Lepton Univ ersality (LU) of Standard Model in neutrino interactions. Recently several results for B-meson decays (LHCb\, Babar) demonstrated hints of possible LU violation.\n The tau neutrinos are produced in the Ds meson decays to tau\, Ds -> tau + nu_tau\, and the cascade decay of the tau\, tau-> x + n u_tau. DsTau experiment has been proposed to study the tau neutrino produc tion at CERN SPS. It will measure the Ds production differential cross-sec tion in proton and tungsten interactions. This will allow reducing of the uncertainty due to the tau neutrino flux in the DONUT result from 50% t o 10% . The peculiar Ds cascade decay topology ("double kink") in a few mm range will be detected by nuclear emulsion tracker thanks to its excel lent spatial resolution (~50nm).\nIn 2016 and 2017\, we made test beam exp osures of nuclear emulsion modules at CERN SPS 400GeV/c proton beam. A pil ot run in August 2018 and physics run in 2021 are scheduled.\n In this tal k\, the status and prospects of the DsTau project as well as a review of t he modern nuclear emulsion technique and the methods of its data analysis will be presented.\n\nhttps://indico.particle.mephi.ru/event/22/contributi ons/1161/ LOCATION:Hotel Intourist Kolomenskoye 4* Alekseevskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1161/ END:VEVENT BEGIN:VEVENT SUMMARY:Environmental decoherence in atmospheric neutrinos with IceCube DTSTART;VALUE=DATE-TIME:20181022T124000Z DTEND;VALUE=DATE-TIME:20181022T151000Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1278@cern.ch DESCRIPTION:Speakers: Thomas Stuttard (Niels Bohr Institute)\nDissipative interactions between neutrinos and the environment in which they propagate lead to quantum decoherence. Such an environment is predicted by quantum gravity models featuring a 'foamy' space-time structure. Environmental dec oherence degrades the interference between neutrino states that is respons ible for neutrino oscillations\, resulting in exponential damping of oscil lation probability with propagation distance. The IceCube detector at the South Pole measures atmospheric neutrinos that have traversed a range of d istances\, up to 12\,742 km for neutrinos crossing the Earth’s diameter\ , making it sensitive to decoherence effects. In this poster\, a phenomeno logical model of neutrino environmental decoherence and the resulting sign al in IceCube is presented\, and the measurement sensitivity estimated for a 6 year data sample.\n\nhttps://indico.particle.mephi.ru/event/22/contri butions/1278/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1278/ END:VEVENT BEGIN:VEVENT SUMMARY:Superheavy objects composed of nuclear and dark matter DTSTART;VALUE=DATE-TIME:20181022T124000Z DTEND;VALUE=DATE-TIME:20181022T151000Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1192@cern.ch DESCRIPTION:Speakers: Vakhid Gani (National Research Nuclear University ME PhI (Moscow Engineering Physics Institute)\, 115409 Moscow\, Russia)\nWe c onsider a model of $OHe$ atomic dark matter formed by Coulomb binding of t he stable double charged massive $O^{--}$ particles with nuclei of primord ial helium.

Anisotropic transverse flow is among the key observables to study the properties of matter creat ed in such collisions.\n\nThe CBM performance for anisotropic flow measure ments is studied with Monte-Carlo simulations using gold ions at SIS-100 e nergies with lab momentum of 3.5-12 AGeV/c employing different heavy-ion e vent generators. Various combinations of CBM detector subsystems are used to investigate the possible systematic biases in flow measurement and to s tudy the effects of detector azimuthal non-uniformity. The resulting perfo rmance of CBM for flow measurements is demonstrated for different harmonic s of identified charged hadron anisotropic flow as a function of rapidity and transverse momentum in different centrality classes.\n\nThe measuremen t techniques developed for CBM were also validated with the experimental d ata recently collected by the NA61/SHINE experiment at CERN SPS for Pb-Pb collisions at the beam momenta 13 and 30 AGeV/c (the first energy point is close to the top SIS-100 energy). This is also of importance for CBM perf ormance studies\, because both CBM and the NA61/SHINE are fixed target exp eriments and have a similar Projectile Spectators Detector (PSD) as a part of their setup.\n\nhttps://indico.particle.mephi.ru/event/22/contribution s/1282/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1282/ END:VEVENT BEGIN:VEVENT SUMMARY:THE ADAPTIVE-MODULAR TECHNIQUE FOR PRE-PROJECT SIMULATION THE TRAN SPORTATION CHANNELS OF THE RELATIVISTIC CHARGED-PARTICLE BEAMS DTSTART;VALUE=DATE-TIME:20181022T124000Z DTEND;VALUE=DATE-TIME:20181022T151000Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1342@cern.ch DESCRIPTION:Speakers: German Averyanov (National Research Nuclear Universi ty (MEPhI))\nConsidered the numerical simulation technique which providing optimum beam parameters at the transport channel output of electron accel erator.

They are possible c andidates not only to dark matter\, but to supermassive black holes\, grav itational waves events from black hole merger and others. However\, recent ly there appeared constraints on PBH abundance from different observations (including those from gravitational microlensing). The present work is de voted to the model of a PBH cluster in which these constraints (part of th em) can be avoided. In this work we investigate effect of gravitational m icrolensing for PBH\, strongly constraining single PBH abundance. Analyses of data on respective observation for a cluster can remove not only const raints on them\, but it makes possible to test this model distinguishing i t from the model of single PBHs.\n\nhttps://indico.particle.mephi.ru/event /22/contributions/1193/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1193/ END:VEVENT BEGIN:VEVENT SUMMARY:Overview of the Compressed Baryonic Matter experiment at FAIR DTSTART;VALUE=DATE-TIME:20181025T142500Z DTEND;VALUE=DATE-TIME:20181025T144500Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1305@cern.ch DESCRIPTION:Speakers: Viktor Klochkov (GSI Helmholtzzentrum für Schwerion enforschung)\nIn this talk an overview of the heavy-ion program and the st atus of the Compressed Baryonic Matter (CBM) experiment at the future Faci lity for Antiproton and Ion Research (FAIR)\, which is being under constru ction in Germany\, will be given.\n\nhttps://indico.particle.mephi.ru/even t/22/contributions/1305/ LOCATION:Hotel Intourist Kolomenskoye 4* Alekseevskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1305/ END:VEVENT BEGIN:VEVENT SUMMARY:Сompact x-ray spectrometer based on thermoluminescent detectors DTSTART;VALUE=DATE-TIME:20181022T124000Z DTEND;VALUE=DATE-TIME:20181022T151000Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1343@cern.ch DESCRIPTION:Speakers: Gayar Salakhutdinov ()\nSingle-channel compact noise -proof spectrometer (Ø 5х10 mm) is based on the absorption filter method . Spectrometer is an assembly of thermoluminescent detectors made of lithi um fluoride LiF\, that are placed one after another\, which are also used as filters for X-ray spectrum selection. Spectrometer has been developed f or measuring X-ray spectra of micropinch-discharge plasma in the energy ra nge of 1−25 keV. The thermoluminescent LiF detectors are most attractive for use in plasma diagnostics. The thermoluminescent LiF detectors are i mmune to electromagnetic interference\, practically insensitive to ultravi olet radiation\, and do not have a dead surface layer\; at the same time\, their response is linear in a wide dynamic range of the absorbed radiatio n dose (from 20 mSv to 10 Sv).

The purpo se of this analysis is search for states with enhanced radii in isobar-ana log excited states of triplet A=12: $^{12}$B – $^{12}$C – $^{12}$N.\n\ nThere is experimental work [1] where halo was observed for 2 states of $^ {12}$B: 2¯\, 1.67 MeV and 1¯\, 2.62 MeV. To check this result new experi mental data $^{11}$B(d\,p)$^{12}$B was obtained at E$_{d}$ = 21.5 MeV [5\, 6]. On base of ANC analysis of this new data [5\,6]\, neutron halo existen ce was confirmed for the 2¯\, 1.67 MeV and 1¯\, 2.62 MeV states in $^{12 }$B. An unexpected result was obtained for the unbound 3¯\, 3.39 MeV stat e\, which is 19 keV above the neutron emission threshold. Its halo radius was also found to be increased and equal to ~ 6.5 fm [5\,6]. This result c an be considered as an evidence of the halo-like structure in this $^{12}$ B state.\n\nWhat can we expect in isobar-analog states in $^{12}$C and $^{ 12}$N? Are these states also characterized by enhanced radii? To check thi s prediction\, preliminary analysis of existing $^{12}$C($^{3}$He\,t)$^{12 }$N and $^{12}$C($^{3}$He\,$^{3}$He’)$^{12}$C experimental data using Mo dified diffraction model (MDM\, [3\,4]) was done. \n\n1.

But antineutrino reactor spectr a (formed by main fuel isotopes) are characterized by large uncertainties in the total -spectrum that lead to very serious problem in understanding of neutrino oscillation results. The reactor spectrum is known with ~ (4- 5)% -precision and this errors dramatically rise up to tens persents at mo re higher energies. [1-4].\n\nThe proposed scheme is based on activation o f 7Li in the reactor neutron flux and transport of the fast beta-decaying 8Li isotope toward a remote neutrino detector and back in the closed loop to the reactor for the next activation in the continuous cycle. Well inves tigated neutrino spectrum of 8Li is hard: with maximal energy up to 13 Me V. For increasing of a hard lithium antineutrinos part in the total spectr um we propose to construct a being pumped reservoir near the neutrino det ector. This novel type of the source will ensure not only harder neutrino spectrum in the detector volume but also an opportunity to register neut rino interaction at different summary spectrum hardness varying smoothly ( without stop of the experiment) a rate of 8Li (or it's chemical compound) pumping in the closed loop [5\, 6].\n\nThe strong advantage is that lithiu m component of the spectrum is well known and this fact allows to decrease significantly the count errors [7\, 8]. The rate of neutrino detector cou nts in such hard flux will rise strongly compare to rate from reactor comp onent. One more advantage is to use compact detector (with volume about ~ cubic meter ) that is exclusively important for realization of the experim ent. \n\nThe simulation of the possible experiment for search of sterile n eutrinos (the reaction of inverse beta decay) with ∆m2 ~1 eV2 reveals t he promise to detect reliable the disappearance of electron antineutrinos. The detailed results for (3+1) and (3+2)-model are presented and discusse d. It is proposed the variant of short base line oscillation experiment ba sing on the considered antineutrino source.\n\n 1.

Unlike had rons\, direct photons are produced in all stages of a nucleus-nucleus coll ision and escape freely from the hot zone. Prompt direct photons can be em itted in pp\, p-Pb and Pb-Pb collisions and provide means to test the init ial stage of AA collision. The spectrum and collective flow of thermal di rect photons carry information about the temperature and space-time evolut ion of the emitting medium.\n\nThe ALICE experiment at LHC reconstructs ph otons via complementary methods\, using the ALICE electromagnetic calorime ters and the central tracking system identifying photons converted to e+e- pairs in the material of the inner barrel detectors. Applying different t echniques\, one can measure photons in a wide range of transverse momenta. In addition\, since calorimetric and tracking approaches have practically independent systematic uncertainties\, their comparison provides a reliab le cross-check. In this talk we review recent ALICE results on direct phot on production in pp\, pA and AA collisions and compare to available data a t SPS and RHIC energies.\n\nhttps://indico.particle.mephi.ru/event/22/cont ributions/1321/ LOCATION:Hotel Intourist Kolomenskoye 4* Moskvorechye 1 hall URL:https://indico.particle.mephi.ru/event/22/contributions/1321/ END:VEVENT BEGIN:VEVENT SUMMARY:Why the hydrodynamics is valid at early stage of heavy-ion collisi ons?

The hy drodynamic scenario is based on the assumptions of fast equilibration and almost isentropic expansion of the matter. Then\, it employs the equation of state (EOS) which links pressure to energy density. Microscopic calcula tions show that (i) the matter expands with the constant entropy-per-baryo n ratio and (ii) with the constant pressure to energy density ratio alread y at very early times\, when the matter is not in local chemical and therm al equilibrium yet.

The sources of the first type correspond to the initial strings formed in a ha dronic collision. The sources of the second type imitate the appearance of the emitters of a new kind resulting from interaction (fusion) of the ini tial strings. The model enabled to describe effectively the influence of t he string fusion effects on the strength both the $n$-$n$ and the $p_{T}$- $n$ correlations. Modification of the model to the analogue of the "core-c orona" mechanism allows to take into account event selection criteria base d on centrality and perform a comparison with existing experimental data o n correlation measurements in nucleus-nucleus collisions at LHC energies.

Recently new data for Pb-Pb collisions were collected by the NA61/SHINE experiment\ndu ring the Pb-ion beam energy scan program at the SPS. This motivated a new analysis of the\navailable NA49 data\, based on modern flow measurement te chniques that will also utilize the\nspectator fragments for reaction plan e determination.\nThe new results on directed and elliptic flow in Pb-Pb c ollisions at beam energy of 40 A GeV\nrecorded with the fixed target exper iment NA49 at CERN SPS are presented. Event\nclassification is based on th e multiplicity of produced particles as well as on the energy of the\nproj ectile spectators using the procedure implemented within the Centrality Fr amework\ndeveloped for the future CBM experiment at FAIR. To account for t he azimuthal asymmetry of\nthe fixed target setup of the NA49 experiment\, a three-subevent technique is used for the\ndetermination of the reaction plane resolution. The reaction plane is estimated both from the\nazimutha l asymmetry of the produced particles measured with the NA49 TPCs as well as by\nusing the transverse granularity of the NA49 forward VETO calorimet er. Corrections for the\ndetector acceptance anisotropy in the transverse plane are applied using an extension of the\nQn-Corrections Framework deve loped originally for the ALICE experiment at the LHC.\nThe results are com pared with those previously obtained by the experiments STAR at RHIC\nand NA49 at the SPS.

Analytic al approaches\, based on the solution of the Grad-Shafranov equation\, can only provide a stationary one-dimensional picture of what is happening.\n \nThe purpose of this work is to combine the above two approaches\, using the plasma configuration and its magnetic field\, obtained by solving the Grad-Shafranov equation\, as the initial conditions for the magnetohydrody namic modeling of a jet. The dynamics of jet propagation through the surro unding space was investigated\, morphology similar to the morphology of th e observed jets was obtained.

Observation o f the same distribution of jets also does not provide detailed information about the physical parameters of both the jets themselves and their envir onment. Interaction with these possibilities is acquired by attempts to re create astrophysical conditions by means of laboratory experiments in whic h scaling plasma parameters close to those observed in young jet stars can be achieved. Numerical modeling makes it possible to verify the theoretic al models of these processes\, making it possible to identify parameters t hat are inaccessible to observation.\n\nIn this work\, a numerical simulat ion of the propagation of a plasma bunch in the experimental facility PF-3 and in astrophysical jets was carried out to determine the parameters inf luencing the development of this bunch. The measurement process was starte d at various initial parameters of the system\, after which there was a de pendence on these parameters\, as a rule\, at the initial and final moment s of time. An analytical estimate of the collimation angle was also obtain ed.

Synthesis of SHN with Z>118 imp lies the use of the heavier than 48Ca beam particles (50Ti\, 54Cr etc.).\n In this lecture\, the durability of the entrance window working at high th e intensity of heavy ion beams is considered. The durability of the entran ce window is estimated as the result of the action of an intense heavy ion beam\, such as sputtering\, radiation damage and temperature [2]. The ass essments of these actions that determine the durability of the entrance wi ndow are discussed. The temperaturstrong texte of the entrance window is c alculated as a function of time in the conditions of its pulsed heating by means of a heavy ion beam\, followed by radiative cooling with radiation emitted from its surface. The entrance window temperatures are calculated for heavy ion beams\, such as 48Ca\, 50Ti\, 54Cr and 58Fe\, with their int ensities expected for the DC-280 accelerator. With these calculations of t he temperature dependences against the time of the beam action the optimal parameters of the entrance window operation is chosen. Literature.\n1. Yu .Ts.

In most works on quan tum cosmology it is accepted that the wave function defines the probabilit y amplitude for the Universe to have some space geometry\, or to be found in some point of the Wheeler superspace. It seems that the wave function g ives maximally objective description compatible with quantum theory. Howev er\, the probability distribution does not depend on time and does not tak e into account the existing of our macroscopic evolving Universe. What we wish to know is how quantum processes in the Early Universe determined the state of the present Universe in which we are able to observe macroscopic consequences of these quantum processes. The picture that can be obtained in the Wheeler – DeWitt quantum geometrodynamics is compared with that that of the extended phase space approach to quantization of gravity. We s hall discuss how the wave function can be chosen among all possible soluti ons of the Wheeler – DeWitt (or Schrödinger) equation\, if it does not depend on a reference frame\, and what stage of the Universe evolution it describes.\n\nhttps://indico.particle.mephi.ru/event/22/contributions/1086 / LOCATION:Hotel Intourist Kolomenskoye 4* Moskvorechye 1 hall URL:https://indico.particle.mephi.ru/event/22/contributions/1086/ END:VEVENT BEGIN:VEVENT SUMMARY:EXO-200 results DTSTART;VALUE=DATE-TIME:20181024T061500Z DTEND;VALUE=DATE-TIME:20181024T063000Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1224@cern.ch DESCRIPTION:Speakers: Vladimir Belov ()\nEXO-200 is dedicated for study of the double beta decay of $^{136}$Xe using 200kg of enriched xenon.

It is by 3-4 orders greater than the energy of a large solar flare\, and\, apparently\, the energy of the protons accelerated in these stellar flares can significantly exceed the energy of the particles registered fro m flares on the Sun.

These effects can be tak en into account by solving the semiclassical backreaction equations \n \n $ G^{\\mu}_{\\nu}=8 \\pi \\langle T^{\\mu}_{\\nu} \\rangle\, \\qquad \\qqu ad \\qquad \\qquad (1)$ \n \nwhere $\\langle T^{\\mu}_{\\nu} \\rangle$ is the expectation value of the stress-energy tensor operator for the quantiz ed fields.\n \nThe main difficulty in the theory of semiclassical gravity is that the vacuum polarization effects are determined by the topological and geometrical properties of spacetime as a whole or by the choice of qua ntum state in which the expectation values are taken. It means that calcul ation of the functional dependence of $\\langle T^{\\mu}_{\\nu} \\rangle_{ ren}$ on the metric tensor in an arbitrary spacetime presents formidable d ifficulty. Only in some spacetimes with high degrees of symmetry for the c onformally invariant fields $\\langle T_{\\mu \\nu} \\rangle_{ren}$ can be computed and equations of the theory of semiclassical gravity can be solv ed exactly. Let us stress that the single parameter of length dimensionali ty in problem (1) is the Planck length $l_{\\small PL}$. This implies that the characteristic scale $l$ of the spacetime curvature (which correspond s to the solution of equations (1) can differ from ${l_{ \\small PL}}$ onl y if there is a large dimensionless parameter. As an example of such a par ameter one can consider a number of fields the polarization of which is a source of spacetime curvature (*it is assumed\, of course\, that the chara cteristic scale of change of the background gravitational field is suffici ently greater than $l_{\\small PL}$ so that the very notion of a classical spacetime still has some meaning*). In the case of massive field\, the ex istence of an additional parameter $1/m$ does not increase the characteris tic scale of the spacetime curvature $l$ which is described by the solutio n of equations (1) (*the characteristic scale of the components $G^{\\mu}_ {\\nu}$ on the left-hand side of equations (1) is $1/l^2$\, on the right-h and side - ${l_{\\small PL}}^2/(m^2 l^6)$)*. For the massless quantized f ields such a parameter can be the coupling constants of field to the curva ture of spacetime [1]. Another possibility of introducing an additional pa rameter in the problem (1) is to consider the non-zero temperature of quan tum state for the quantized field. It is known (see\, e.g.\, [2]) that in the high-temperature limit (when $T \\gg 1/l\, T$ being a temperature of t hermal state) $\\langle T^{\\mu}_{\\nu} \\rangle$ for such a thermal state is proportional to the fourth power of the temperature $T$.\n\nIn this wo rk an analytical approximation of ${\\langle \\varphi^2 \\rangle}$ for a q uantized scalar field in a thermal state at arbitrary temperature is consi dered. The scalar field is assumed to be both massive and massless\, with an arbitrary coupling $\\xi$ to the scalar curvature\, and in a thermal st ate at an arbitrary temperature $T$. The gravitational background is assum ed to be static spherically symmetric and slowly varying. We have shown th at in such spacetime the effect of vacuum polarization of a quantized scal ar field in the thermal state does not depend on temperature and condition s at infinity.

Most of the exact so lutions constructed within the framework of the general relativity are sta tic or stationary configurations. This is due to the objective complexity of solving the Einstein equations under the assumption of nonstationarity. We present an approach to constructing nonstationary configurations of a spherically symmetric nonlinear real scalar field and the electromagnetic field\, which are assumed both to be minimally coupled to gravity. It is b ased on the separation of one invariant equation\, written in terms of the characteristic function and scalar field potential. Using the proposed me thod\, an exact nonstationary solution with a nontrivial topology of space -time will be constructed.\n\nhttps://indico.particle.mephi.ru/event/22/co ntributions/1077/ LOCATION:Hotel Intourist Kolomenskoye 4* Moskvorechye 1 hall URL:https://indico.particle.mephi.ru/event/22/contributions/1077/ END:VEVENT BEGIN:VEVENT SUMMARY:On Kasner solution in Bianchi I $f(T)$ cosmology DTSTART;VALUE=DATE-TIME:20181022T124000Z DTEND;VALUE=DATE-TIME:20181022T151000Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1098@cern.ch DESCRIPTION:Speakers: Maria Skugoreva ()\nRecently cosmological dynamics o f anisotropic Universe in $f(T)$ gravity became an area of intense investi gations.

In this talk\, we review the most recent ALICE results on the production of different light-flavor hadrons\, including transverse momentum spectra\, y ields\, nuclear modification factors and particle ratios in pp\, p-Pb\, Xe -Xe and Pb-Pb collisions at LHC energies. Having different masses\, quark content and lifetimes\, light flavour hadrons do not only serve as general observables in the soft sector\, but also play an important role as high transverse momentum probes and signatures of the onset of collectivity in high-multiplicity collisions of small systems. Production of light flavour hadrons containing strange quarks is enhanced from pp to p-Pb and Xe-Xe/P b-Pb collisions. The strength of such an enhancement depends on the partic le strangeness content\, but it is also present for phi(1020) mesons with hidden strangeness. The production of short-lived resonances with lifetime s comparable to that of the fireball is suppressed in central heavy-ion co llisions\, which can be attributed to rescattering of daughter particles i n the dense hadronic medium. Transverse momentum spectra for light hadrons become harder at higher multiplicities in all collision systems\, which i s likely the result of radial flow. The baryon-to-meson ratios evolve with event multiplicity and demonstrate qualitatively similar behavior in pp\, p-Pb and Xe-Xe/Pb-Pb collisions at high multiplicities. Production of lig ht hadrons is similarly suppressed at high transverse momenta in central P b-Pb collisions\, while no significant modification is found in p-Pb colli sions.

But the intrinsically \nnonlinear characte r of gravitational eauations makes solving them a very difficult and probl emticc task. \nThis is why the investigations of the hypersurfaces where t he matter energy-momentum tensor undergoes some \ndiscontinuities are so i mportant. The physically interesting discontinuities are jumps (they can b e viewed as \nan idealization of the shock waves) and thin shells (i.e.\, $\\delta$-function distributions\, describing some \nidealized matter sour ces including the potential barriers between two different phases during c osmological phase \ntransitions). \n\nThe thin shell formalism in General Relativity was elaborated by W.Israel. But\, nowadays\, the Einstein's the ory \nis no more the ultimate theory of gravitation. The necessity to incl ude into the gravitational action itegral \nthe terms\, quadratic (and hig her order) in curvature tensor\, was foreseen by A.D.Sakharov 50 years ago (induced \ngravity)\, and it was confirmed in the series of works by A.A. Starobinsky and Ya.B.Zel'dovich\, L.Parker and S.Fulling\, \nA.A.Grib and V.M.Mostepanenko and many others while considering the quantum processes o f particale creation in \ncosmology. The selfconsistent treatment of the b lack hole evaporation discovered by S.W.Hawking also requires inclusion \n of such nonliner terms into the action integral. Surely\, the first step i s to consider the so called quadratic gravity. \nIn this case the gravitat ional Lagrangian is the most general quadratic form constructed from the R iemann curvature \ntensor and its convolutions (the Ricci tensor and the c urvature scalar)\, it includes also the Einstein-Hilbert linear \nterm (th e curvature scalar) and the cosmological term. It appeared that the quadra tic gravity allows the existence of \nthe hypersurfaces more singular than the thin shells. Namely\, the double layers (i.e.\, $\\delta^{\\prime}$-d istributions) \nwhich are completely forbidden in General Relativity. The general thery of such double layers was elaborated quite \nrecently by J.S enovilla et al. \n\nHere we resrict ourselves to investigation of the so c alled Weyl-Einstein gravity\, the specific case of the generic \nquadratic gravity\, when all the quadratic terms are just consituents of the square of the Weyl tensor. This is done \npartly because the additional symmetry leads to the less restrictive matching conditions (and\, hence\, deserves separate \nconsideration)\, and also of the importance of this very combi nation for the cosmological particle creation processes. \nFor the sake of simplicity (and the physically transparent interpretation) we constructed the theory of the spherically \nsymmetric double layers and thin shells. The applications are the examples of the thin shells without double layers \nand double layers without thin shells. Also we showed that the matching conditions forbid the formation of the null \ndouble layers in Weyl+Einst ein gravity.\n\nhttps://indico.particle.mephi.ru/event/22/contributions/10 82/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovskiy-1 hall URL:https://indico.particle.mephi.ru/event/22/contributions/1082/ END:VEVENT BEGIN:VEVENT SUMMARY:De Sitter and Power-law Solutions in Non-local Gauss-Bonnet Gravit y DTSTART;VALUE=DATE-TIME:20181024T065000Z DTEND;VALUE=DATE-TIME:20181024T071000Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1087@cern.ch DESCRIPTION:Speakers: Ekaterina Pozdeeva ()\nThe cosmological dynamics of a non-locally corrected gravity theory\, involving a power of the inverse d'Alembertian\, is investigated.

By using the same EOS\, some theoretical physicists h ave been trying to construct traversable wormholes. Recently\, Ananda and Bruni [Phys.Rev.D74:023523\,2006] have proposed quardratic EOS to describe homogeneous and inhomogeneous cosmological models. In this\, article we e xplore the possibility that the wormholes be supported by quardratic EOS. We have found a series solution of Einstein equations describing\nwormhole for a matter source that is characterized by quardratic EOS.\n\nhttps://i ndico.particle.mephi.ru/event/22/contributions/1092/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1092/ END:VEVENT BEGIN:VEVENT SUMMARY:(2+1) dimensional cosmological models in f(R\, T) gravity with Λ( R\, T) DTSTART;VALUE=DATE-TIME:20181022T124000Z DTEND;VALUE=DATE-TIME:20181022T151000Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1093@cern.ch DESCRIPTION:Speakers: Praveen Kumar (Department of Mathematics\, R.T.M.Na gpur University Nagpur)\nWe intend to study a new class of cosmological mo dels in f(R\, T) modified theories of gravity\, hence\ndefine the cosmolog ical constant Λ as a function of the trace of the stress energy-momentum- tensor T and\nthe Ricci scalar R\, and name such a model Λ(R\, T) gravity where we have specified a certain form of\nΛ(R\, T).

In simplest and most widespread realization of the inflationar y scenario\, only one dimensional parameter plays essential role - the Hub ble parameter $H$. \n If a compact space is involved into considerat ion\, another dimensional parameter - an extra space size $l$ - appears. T here are two opposite cases $l\\gg H^{-1}$ and $l\\ll H^{-1}$. The second case is not very interesting because the Kaluza-Klein excitations are too massive to be excited during the inflation. Much more promising is the fi rst case which leads to the energy storage "inside"\\ the extra space in t he form of its fluctuations. It will be shown here that the first case con tradicts observations.

Normally it is taken for granted that the notion “halo” c ould not be applied to unstable nuclei. However\, if the time of life T of a particular nucleus is much larger than the characteristic time τ of fl ight of the escaping neutron\, there is no difference between stable and u nstable nuclei. As for $^{7}$He the ratio T/τ ≈ 7 we looked for data wh ich could provide some information on the halo – like structure of $^{7} $He. We applied the Modified diffraction model MDM [2-4] to the charge – exchange reactions $^{6}$Li(t\,$^{3}$He)$^{6}$He [5] and $^{7}$Li(t\,$^3$ He)$^{7}$He [6]. According to MDM the difference of the RMS of the states under study is determined by the difference of the corresponding diffracti on radii taken from the differential cross-sections under study. We found that the radius of $^{7}$He is R$_{rms}$ = 2.37±0.38 fm. This value is cl ose to those of $^{6}$He and $^{8}$He 2.48±0.03 fm and 2.52±0.03 fm [1]. The result supports suggestion that neutrons outside $^{4}$He occupy the same orbitals and indicates to smooth transition between halo and skin. Th e phase distributions of the fragments emitted in the reactions with stopp ed pions on $^{9}$Be and $^{11}$B [7\, 8] showed that the main $^{7}$He de cay configurations are $^{6}$He$_{gr.st}$ + n and $^{6}$He* + n confirming the complicated halo – like of $^{7}$He. \n\n1.

The forward regions\, corresponding to the endcaps of the detectors\, are the most affected parts. In the CMS exp eriment\, to cope with the higher event rates and larger radiation doses\, triple-layer Gas Electron Multipliers (GEM) will be installed in the muon endcaps. Triple-GEM chambers will complement the existing Cathode Strip C hambers\, leading to a better identification of the muon tracks and a redu ction of the trigger rate due to the suppression of fake candidates.

In the experiment the sec ondary light nuclei with momenta above kinematic limit\nof NN-interactions have been detected. The transfering from observed yields of patticles to the invariant cross section made on the base of detailed simulation for pr opagation of particles and nuclei through the beam line and the FODS det ectors in the framework of Geant4.

At the same time\, the two-step decay of the same nucleus ($A$ → $a_1$ + $A_1$ → $a_1$ + $a_2$ + $A_2$ ) described by the Feynman diagram\, including at the first step the flight of the real particle $A_1$ from the nucleus $ A$ with the formation of the virtual state of the intermediate nucleus $A_ 1$\, described by the Green function $G_{A_1}$ of this nucleus whose pole lies in the region of negative values of the kinetic energy $T_{A_1}$ of t he nucleus $A_1$\, and at the second step the decay of the nucleus $A_1$ w ith the formation of the real particle $a_2$ and the real daughter nucleus $A_2$\, is possible if the heat $Q_2$ of the decay of the nucleus $A_1$ s atisfies the condition $Q_2$ >│$Q_1$│\, when the total heat $Q$ of the analyzed decay\, defined as $Q$ = $Q_1$ + $Q_2$\, is positive. \nFor the first time\, the named above virtual mechanism of the two-step decay was successfully used [1] to describe the true double β-decay of an even-even parent nucleus ($A$\, $Z$) with the formation of a daughter nucleus ($A$\ , $Z ± 2$) and flight of two electrons and two electron antineutrinos or of two positrons and two electron neutrinos\, when one-step β-decay of nu cleus ($A$\, $Z$) with the formation of an intermediate nucleus ($A$\, $Z ± 1$) is forbidden. This situation was realized because of the influence of Cooper pairing of two protons and two neutrons in the parent nucleus ($ A$\, $Z$)\, when the heats $Q_1$ and $Q_2$ of the single β-decays of the nucleus ($A$\, $Z$) and the virtual state of the intermediate nucleus-isob ar ($A$\, $Z ± 1$) satisfy the conditions $Q_1$ │$Q_1$│and $Q$ = $Q_1 $ + $Q_2$ > 0. \nIn [2]\, the phenomenon of two-proton radioactivity also caused by the proton pairing effects was predicted for series of neutron- deficient nuclei ($A$\, $Z$) even in $Z$. In [3]\, the presentation about virtual two-step mechanism for the two-proton decay of nuclei was first u sed unlike to the earlier proposed concept [4] of two-proton decay of the nucleus ($A$\, $Z$) with the simultaneous flight of the daughter nucleus ( $A-2$ \, $Z-2$) and two protons. This allowed to describe the two-proton w idths and the energy and angular distributions of two emitted protons in t he superfluid model of atomic nucleus in a consistent manner. \nFinally\, it can be shown that the appearance of long-range $α$-particles emitted as third (fourth) particles in the true ternary (quaternary) fission of c ompound nuclei ($A$ \, $Z$) produced in nuclear reactions with slow neutro ns can be described successively with usage the stationary mechanism of na med above reactions associated with the appearance of virtual states of in termediate nuclei formed in the two-step (three-step) nuclear decay of com pound nuclei ($A$ \, $Z$) in contrast to the nonstationary nonadiabatic me chanism of [5].\n\n1.

FIT will consist of two arrays of Cherenkov radiators (T0+ ) and a large segmented scintillator ring (V0+). FIT will serve as the mai n luminometer\, as well as the detector which will determine collision tim e\, multiplicity\, centrality\, and reaction plane in ALICE during Runs 3 and 4. Among the many challenges of this project are: a high dynamic range (0.4 to 250 MIP (minimum interaction particle) amplitude for T0+\, 0.5 to 600 MIP amplitude for V0+)\, operation with the sustained bunch crossing of 25 ns\, time resolution below 50 ps\, signal processing and trigger gen eration within 205 ns. Light generated in the scintillators of the V0 will be detected by 48 Hamamatsu fine mesh 2” PMTs. The Cherenkov radiators will be coupled to 52 modified Planacon light sensors. The photocathode si ze of XP85012/FIT-Q is 53x53 mm2. The 64 anodes at the base of a chevron-s haped assembly of MCP plates are divided into 4 equal sectors matching the radiator quadrants. To reach the required lifetime and dynamic range\, Pl anacons will operate at the output amplitude of 10 mV/MIP (charge 0.63 pC/ MIP) requiring special cabling and low-noise fast electronics. The time i nformation will be extracted from a CFD and digitized with the accuracy of better than 50 ps over the entire dynamic range. The input charge will be integrated and measured by an ADC. The first prototype of a Cherenkov mod ule and the full chain of front-end electronics were installed inside of t he ALICE magnet and are part of the Run 2 data collection since 2016. \nTh is work was supported by INR RAS and NRNU MEPhI within the Russian activit ies in the ALICE upgrade and by the Ministry of Education and Science of R ussian Federation\, contract No14.610.21.0003.\n\n[1] W.H.

The most know processes of this type are n eutrino and neutral kaon oscillations\, which are described nowadays only in an eclectic quantum-mechanical approach. The experimental setting of th ese processes requires one to adjust the rules of passing to the momentum representation in the Feynman diagram technique in accordance with it\, wh ich leads to a modification of the Feynman propagator in the momentum repr esentation. The approach does not make use of wave packets\, both initial and final particle states are described by plane waves\, which simplifies the calculations considerably. The description is very similar to the usua l one performed in the framework of the Feynman diagram technique in the m omentum representation\, where the standard propagators are replaced by th eir modified versions. We demonstrate the validity of the formalism by app lying it to three processes: neutrino oscillations\, unstable particle dec ay and neutral kaon oscillations.

In th is report we present the results of projections of FCNC searches in top qu ark interactions to the FCC-hh conditions based on Monte-Carlo simulation of FCC-hh detector.\n\nhttps://indico.particle.mephi.ru/event/22/contribut ions/1160/ LOCATION:Hotel Intourist Kolomenskoye 4* Alekseevskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1160/ END:VEVENT BEGIN:VEVENT SUMMARY:Gravitational waves DTSTART;VALUE=DATE-TIME:20181024T111500Z DTEND;VALUE=DATE-TIME:20181024T114500Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1357@cern.ch DESCRIPTION:Speakers: Vitor Cardoso (Instituto Superior Técnico)\nhttps:/ /indico.particle.mephi.ru/event/22/contributions/1357/ LOCATION:Hotel Intourist Kolomenskoye 4* Alekseevskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1357/ END:VEVENT BEGIN:VEVENT SUMMARY:New Results from Multi-quark Exotic States Searches at D0 Experime nt DTSTART;VALUE=DATE-TIME:20181026T073500Z DTEND;VALUE=DATE-TIME:20181026T075000Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1166@cern.ch DESCRIPTION:Speakers: Aleksei Popov ()\nRecent results from a search for m ulti-quark exotic states at DZero experiment (FNAL\, USA) are presented in this talk.\nThis includes the new data for possible tetraquark state X(55 68) in the channels with semileptonic decays of B_s mesons.\nAlso\, result of the J/\\psi \\pi system analysis and evidence for exotic charged charm onium-like state Z_c(3900) in semi-inclusive\nweak decays of b-flavored ha drons are presented as well.\n\nhttps://indico.particle.mephi.ru/event/22/ contributions/1166/ LOCATION:Hotel Intourist Kolomenskoye 4* Alekseevskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1166/ END:VEVENT BEGIN:VEVENT SUMMARY:Bottomonium and bottomonium-like states at the Belle experiment DTSTART;VALUE=DATE-TIME:20181026T081500Z DTEND;VALUE=DATE-TIME:20181026T083000Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1172@cern.ch DESCRIPTION:Speakers: Roman Mizuk ()\nBottomonia are heavy mesons consisti ng of b and b-bar quarks\, while bottomonium-like states are mesons contai ning b and b-bar quarks but having properties unexpected for bottomonia.

The NA64 experiment at CERN S PS accelerator is aimed at probing an unexplored parameter space of kineti c gamma-A' mixing strength and mass values of A'. Experiment utilizes 100 GeV electron beam and the main process is the generation of A' inside an a ctive target via the reaction: e-Z -> e-ZA' which is possible due to gamma -A' mixing. The existence of A' can be determined by presence of missing energy signature events inside the target and subsequent A' decay signatur e events inside downstream calorimeters. The NA64's simulation software pa ckage provides Monte-Carlo modelling for such processes. This work is aime d at developing a Geant4-like implementation of a new A' particle and proc esses corresponding to it's production and decay for the NA64's simulation software package.

The measurements perform ed for a wide range of reactions provide valuable data for studying proper ties of hadronic matter under extreme conditions. They also provide precis e results on hadron production for determining the neutrino flux in long-b aseline neutrino experiments and for more reliable simulations of cosmic-r ay showers.\n\n The primary aim of the experiment is the investigation o f the transition from hadron gas to quark-gluon plasma and the search for associated critical point. A broad region of the phase diagram is probed b y varying energy and size of the collision system (from p+p to Pb+Pb at be am momenta 13A – 150 /158A GeV/c). Various observables\, e.g. quantities measuring event-to-event fluctuations of the particle multiplicity\, whic h are expected to reveal the occurrence of phase transition or critical be havior are examined. The observed non-monotonic pattern in the excitation function of the K+/π+ ratio in NA49 Pb+Pb reactions has been interpreted as the onset of deconfinement. This ratio is currently studied in p+p\, Be +Be and Ar+Sc collisions by NA61/SHINE.\n\nAnalysis of the system-size dep endence of hadron production properties has shown a distinct qualitative c hange in passing from p+p and Be+Be to Ar+Sc system\, which indicates a th reshold for formation of large clusters of strongly interacting matter - t he onset of fireball.\n\nRecently\, the experimental program was extended by measurements of production properties of open charm mesons that are exp ected to provide a better insight into the phase transition behavior of ha dronic matter. For this purpose\, the NA61/SHINE spectrometer was suppleme nted with a Vertex Detector\, which allowed identification of $D^0$ mesons in the first test measurements performed for Pb+Pb collisions at 150A GeV /c.\n\nThis talk will present the recent experimental results and the phys ics program for future measurements beyond 2020\, after the Long Shutdown 2 of the CERN accelerators\, as well as the planned upgrade of the NA61/SH INE facility.\n\nhttps://indico.particle.mephi.ru/event/22/contributions/1 304/ LOCATION:Hotel Intourist Kolomenskoye 4* Alekseevskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1304/ END:VEVENT BEGIN:VEVENT SUMMARY:Разработка жидких органических сци нтилляторов на основе ЛАБ для решения фу ндаментальных и прикладных задач физики нейтрино DTSTART;VALUE=DATE-TIME:20181022T124000Z DTEND;VALUE=DATE-TIME:20181022T151000Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1241@cern.ch DESCRIPTION:Speakers: Denis Kuznetsov ()\nЖидкие органичес кие сцинтилляторы (ЖОС) в настоящее врем я являются единственным материалом\, поз воляющим создавать многотонные сцинтил ляционные детекторы оптимальной геомет рии для исследований в области физики не йтрино.

For example\, a pr omising approach to quantization of gravity based on abandoning Lorentz in variance has been proposed by Horava. At low energies Horava gravity reduc es to a special case of the so-called Einstein-aether theory - a widely st udied phenomenological model\, where Lorentz violation is described by a time-like vector field with unit norm ("aether") that minimally couples to gravity. However a phenomenologically acceptable theory where Lorentz inv ariance is not fundamental\, the latter should appear at low energies as a n emergent symmetry. A possible mechanism ensuring such emergence is provi ded by supersymmetry. \n We consider supersymmetric extension of the Einstein-aether theory. This cannot be realized within the minimal N=1 supergravity which does not allow to define a chiral aether vector superf ield. This problem is resolved in the non-minimal formulation of the N=1 s upergravity. We use the latter formulation to construct a superfield Lagra ngian for the aether field coupled to linearized supergravity. We show tha t the constructed Lagrangian for this model is unique and obtain its boson ic part expanding in the Grassman coordinates. The model is considered als o at the component level. We study supercurrent supermultiplet in the theo ry as an alternative way to prove its uniqueness and to construct fermioni c interaction in the model. The phenomenological consequences of the model are discussed. Extension to the full non-linear Einstein-aether supergrav ity is also briefly outlined.\n\nhttps://indico.particle.mephi.ru/event/22 /contributions/1064/ LOCATION:Hotel Intourist Kolomenskoye 4* Moskvorechye 1 hall URL:https://indico.particle.mephi.ru/event/22/contributions/1064/ END:VEVENT BEGIN:VEVENT SUMMARY:Development of the signal readout and processing ASIC for GEM dete ctors DTSTART;VALUE=DATE-TIME:20181022T124000Z DTEND;VALUE=DATE-TIME:20181022T151000Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1249@cern.ch DESCRIPTION:Speakers: Ivan Bulbakov (NRNU MEPHI)\nDesign approach and stru cture of an Application-Specific Integrated Circuit (ASIC) for multichanne l Gas Electron Multiplier (GEM) detectors are presented.

Than ks to such projects as the Event Horizon Telescope\, LIGO and VIRGO\, eLIS A and others\, it will be possible to obtain observational data and to tes t various theoretical models. Therefore\, it is important to close some ga ps\nin the theories of black holes that have not been resolved in due time . One of these not fully investigated questions is the dyon black hole mod el in the presence of a dilaton field. Black holes with electric and / or magnetic charges are well studied\, and solutions for them are represented by RN metric. However\, in the presence of the dilaton field\, the situat ion becomes much more complicated.\nWe show that there are two classes of solutions that describe static spherically symmetric dyonic dilaton black holes with two nonsingular horizons. The first class includes only the alr eady known solutions that exist for a few special values of the dilaton co upling constant. Solutions belonging to the second class have essentially different properties. They exist for continuously varying values of the di laton coupling constant\, but arise only for discrete values of the dilato n field at the horizon. For each given value of the dilaton coupling const ant\, there may exist several such solutions differing by the number of ze ros of the shifted dilaton function in the subhorizon region and separatin g the domains of singular solutions.\nThe obtained result disproves the ex isting triangular hypothesis that regular dyon-dilaton black holes can exi st only for a certain discrete sequence of the dilaton coupling constant. Since the dilaton coupling constant is an external parameter in this model (and can be specified by a more fundamental theory of gravitation)\, the independence of the discreteness phenomenon from the value of this constan t is a rather important result. The universal nature of the discreteness o f regular solutions can lead to a number of new phenomena in the dyon-dila ton system of black holes.\n\nhttps://indico.particle.mephi.ru/event/22/co ntributions/1078/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovskiy-1 hall URL:https://indico.particle.mephi.ru/event/22/contributions/1078/ END:VEVENT BEGIN:VEVENT SUMMARY:Current status of LZ and LUX Dark Matter Experiments DTSTART;VALUE=DATE-TIME:20181025T133000Z DTEND;VALUE=DATE-TIME:20181025T134500Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1254@cern.ch DESCRIPTION:Speakers: Vladimir Solovov (LIP-Coimbra)\nLUX-ZEPLIN (LZ) is a second-generation dark matter experiment to be installed 1480 m undergro und at the Sanford Underground Research Facility (SURF) in South Dakota\, USA.

First\, they have been studied experimentally for quite a long time\, for which a rich material has been accumulated. Secondly\, with the development of the quark model and nonperturbative methods of quantum chr omodynamics\, such reactions\, as well as the reverse decay processes of m esons into two photons\, were constantly in the field of intensive theoret ical studies.\nA new round of interest in such processes is connected with their possible role as a new source of interactions between leptons and n ucleons. Since in atomic physics there are precise experiments to measure the fine and hyperfine structure of the spectrum\, any new contributions t o the particle interaction operator are important and can be studied exper imentally. The first estimate of the contribution of effective meson excha nges in muonic hydrogen\, which have already appeared\, show that this con tribution can be significant.\nIn this study we extend our analysis to the case of scalar mesons. There are several scalar mesons with the mass near 1 GeV\, which can contribute to the effective muon-proton interaction: f0 (550) (or sigma)\, f0(980)\, a0(980)\, f0(1370). On the basis of quasipote ntial method in quantum electrodynamics we construct the muon-proton inter action amplitudes due to scalar meson exchange.

It allows us to check the standard model and o btain more precise values of fundamental physical constants. The relevance of such research is connected with the experiments carried out by CREMA C ollaboration. In these experiments Lamb shift of 2S and 2P and HFS for muo nic hydrogen and muonic deuterium was obtained by means of laser spectrosc opy. To calculate HFS of muonic ions we use quasipotential method in quant um electrodynamics\, where the bound state of muon and nucleus can be desc ribed by means of Schrodinger equation and the potential is constructed wi th the use of scattering off-shell amplitude. The main contribution to the interaction operator of two particles is given by the well-known Breit Ha miltonian. \nIn perturbation theory infinite series for the interaction op erator of particles includes contributions of different kinds of interacti ons\, primarily electromagnetic. Relativistic corrections of order $\\alph a^6$ and also the contribution of anomalous magnetic moment of muon are kn own in analytical form. \nOne- and two-loop vacuum polarization effects of order $\\alpha^5$ and $\\alpha^6$ in first and second order perturbation theory were obtained in integral form and evaluated numerically. One of th e leading contributions to the HFS is given by the nuclear structure effec t. Such effects can be described by means of two-photon exchange amplitude s. To calculate these amplitudes and also to calculate amplitudes of high er order of $\\alpha$ the approach of projection operator was used. We al so calculate more complicated corrections that involve combined effects of vacuum polarization\, relativism and nuclear structure of order $\\alpha^ 6$. Furthermore the dependance of the calculated contributions on the char ge $Z$ of the nucleus was studied and final numerical values of HFS were obtained.\n\nhttps://indico.particle.mephi.ru/event/22/contributions/1265/ LOCATION:Hotel Intourist Kolomenskoye 4* Alekseevskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1265/ END:VEVENT BEGIN:VEVENT SUMMARY:Graviton-to -photon conversion effect in magnetized relativistic p lasma DTSTART;VALUE=DATE-TIME:20181024T061000Z DTEND;VALUE=DATE-TIME:20181024T063000Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1102@cern.ch DESCRIPTION:Speakers: Ivan Simkin ()\, Konstantin Postnov (Sternberg Astro nomical Institute)\nThe graviton-to-photon conversion effect in a magnetiz ed relativistic lepton plasma is considered. This effect can be important for the possible generation of electromagnetic radiation accompanying coal escence of relativistic compact neutron star -- black hole binaries. The r elativistic electron-positron plasma can be generated near the surface of a rotating magnetized neutron star (a radio pulsar). The formation of a re lativistic compact binary containing a pulsar and a black hole is predicte d by the evolution of massive binary stars. Prior to the coalescence of su ch a binary due to gravitational wave (GW) emission\, a fraction of the GW power can be converted in the plasma outflow into a low-frequency electro magnetic (EM) waves\, which can lead to additional radio power prior to th e coalescence. Using the graviton-to-photon conversion mechanism in an ext ernal magnetic field\, we calculate the fraction of GW power converted int o the EM radiation in the relativistic plasma. The result is found to depe nd on the neutron star spin period $P$\, plasma Lorentz factor $\\gamma$ a nd the cascade multiplicity $\\lambda$\, but independent of the neutron st ar magnetic field: $K\\simeq 10^{-35}(P/1\\mathrm{s})^2(\\gamma/10^5)^2(\\ lambda/10^5)^{-2}$.

The sensitivity required by future neutrino physics implies unpre cedented detector masses\, for which traditional LAr TPC designs face chal lenges e.g. due to the long drift distances of O(10m). In order to efficie ntly drift ionisation electrons\, very High Voltage (HV) and LAr purity ar e required\, which comes along with risks of HV breakdowns with huge power dissipations.\nTo address these issues\, the ArgonCube Collaboration deve loped a novel generation LAr TPC design\, segmenting the total detector vo lume into a number of electrically and optically isolated TPCs sharing a c ommon cryostat. For the charge readout\, a pixelated anode plane is employ ed\, providing unambiguous 3D event reconstruction. To minimize inactive a nd dense material within the TPC a new technology is used for field shapin g\, replacing the classical field cage by a resistive field-shell. In the case of HV breakdown the continuous resistive shell reduces power dissipat ion. The scintillation light readout is achieved by large dielectric plane s inside the field-shell allowing for an efficient detection of prompt sci ntillation light and improved particle identification and trigger efficien cy.

We discuss a finite volume system\, such a s a magnetized neutron star (NS)\, and study the contribution of the surfa ce terms to the evolution of the magnetic helicity. Accounting for the fas t washing out of the chiral imbalance in a nascent NS\, we demonstrate tha t the surface terms contribution can potentially lead to the reconnection of magnetic field lines and subsequent gamma or X-ray bursts observed from magnetars. We derive the additional surface terms originated by the mean spin flux through a volume boundary arising due to macroscopic spin effect s in electron-positron plasma.

Surprisingly\, the hadron resonance gas model (HRGM) is able to perfectly describe the their multiplicities [2 ] under various assumptions. For instance\, one can consider the (anti)nuc lei with a vanishing hard-core radius (as the point-like particles) or wi th the hard-core radius of proton\, but the fit quality is the same for th ese assumptions. However\, it is clear that the hard-core radius of a nucl ei consisting of A baryons or antibaryons must be give by the expression $ R(A) = R(1) A^\\frac{1}{3}$. To implement such a relation into the HRMG we employ the induced surface tension concept [3] and perform a thorough ana lysis of hadronic and (anti)nuclei multiplicities measured by the ALICE co llaboration. The HRGM with the induced surface tension allows us to verify different assumptions on the values of hard-core radii and different sce narios of chemical freeze-out of (anti)nuclei. It is shown that the most s uccessful description of hadrons can be achieved at the chemical freeze-ou t temperature $T_h=150$ MeV\, while the one for all (anti)nuclei is $T_A=1 68$ MeV. Possible explanations of this very high temperature of (anti)nuc lei chemical freeze-out are discussed.\n\n1. J. Adam et al. [ALICE Collabo ration]\, Phys. Rev. C 93\, no. 2\, 024917 (2016). \n\n2.

This\, for the first time\, suggests that quantum vacuum may explain both phenomena\; phenomena for which we ha ve invoked dark matter and phenomena for which we have invoked dark energy . \n\nFurthermore\, as a consequence of the hypothesis of virtual gravitat ional dipoles\, together with the gravitational version of the Schwinger m echanism\, the possibility exists that we live in a cyclic universe with c ycles alternatively dominated by matter and antimatter. Consequently\, at least mathematically\, there is no initial singularity\, there is no need for cosmic inflation and there is an elegant explanation of the matter-ant imatter asymmetry in the universe: our universe is dominated by matter bec ause the previous cycle was dominated by antimatter (and the next cycle wo uld be dominated by antimatter again). \n\nThe eventual evidence of gravit ational effects from the quantum vacuum “enriched” with virtual gravit ational dipoles can be revealed\, among other ways\, through the gravitati onal experiments with antihydrogen at CERN and by the study of orbits of t iny satellites in trans-Neptunian binaries\, for instance UX 25.\n\nhttps: //indico.particle.mephi.ru/event/22/contributions/1090/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1090/ END:VEVENT BEGIN:VEVENT SUMMARY:STAR Highlights and Future DTSTART;VALUE=DATE-TIME:20181025T120000Z DTEND;VALUE=DATE-TIME:20181025T123000Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1271@cern.ch DESCRIPTION:Speakers: Grigory Nigmatkulov ()\nHeavy-ion collisions provide opportunity to explore phase structures of strongly interacting hot and d ense nuclear matter called Quark-Gluon Plasma (QGP).

This detector can capture full Sherrer's ring and therefore can provide t he most effective regustration of scaterred by sample neutrons. The design of the detector allows completely avoiding blind areas. The developed det ectors consisst from linear scintillation counters developed and fabricted in INR RAS [1]. This counters use for light readout a lightguide with dif fuse reflection. The light readout by this method is more effective than t he wavelenght shifting fibers - up to 80 photoelectrons [2-3]. These ring detectors are successfully tested on time-of-flight diffractometers at spa llation source RADEX of INR RAS [3]. The efficiency of thermal neutrons re gistration can reach 70%. It is also possible to create multi-layer detect ors to increase efficiency. We also developed counters with trapezoidal li ghtguide for assembling of the ring detector. This method allows us to ach ieve 0 % of blind areas. This method has patented [4].\n Proposed schemes will make it possible to create highly efficient\, compact and lightweight detectors that do not require high voltage (because used solid-state phot omultipliers).

Powerful 8Li-antineutrino source can be real ized on the base of (n\,gamma)-activation of 7Li isotope and subsequent be ta-decay. The source is a prime perspective owing to the hard antineutrin o spectrum as cross section of neutrino depends at the considered energy p roportional to squared energy and rate of the neutrino interactions will increase strongly. \n\nDifferent neutron sources can be utilized for lithi um activation [1-3]. It can be the high-flux nuclear reactors (in a statio nary mode) enclosed by lithium blanket-converter (i.e.\, the neutrino fact ory in a static regime of operation). The advantages of 8Li antineutrino s pectrum will be more fully utilized in the scheme with pulse reactors\, wh en antineutrino flux from beta-decay of fission isotopes will be separate d in time from neutrino of 8Li decay. Another perspective regime is dynami cal one\, when an activated 7Li is pumped in the close cycle through the a ctive zone of the reactor and further is delivered close to the neutrino d etector. Today significant activity directed to creation of the neutrino f actory based on the tandem of lithium blanket plus an accelerator and neut ron generating target [4-5]. \n\nIt was calculated the efficiency (number of 8Li isotopes per neutron of the neutron source) of such an installation s. It was considered the geometries of lithium blankets. Different types o f blanket matter were considered: the pure lithium in the metallic state a nd lithium chemical compounds. The most preferable is the D2O-solution of LiOD\, which allows to decrease the requirements in mass of high purified 7Li isotope from tens to about three hundreds times [5-7]. It was consider ed the neutron yield from targets (W\, Pb) of the neutrino factory in the “tandem” scheme of proton accelerator (with energy of several hundreds MeV’s) and the expected efficiency of the lithium blanket were obtained . The conception of the proposed lithium source in the “tandem” scheme [8] is included today to the project of the powerful source and proposed for neutrino investigations [4].\nIt was considered the advantages ensured by 8Li source for neutrino experiments.\n\nhttps://indico.particle.mephi. ru/event/22/contributions/1212/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1212/ END:VEVENT BEGIN:VEVENT SUMMARY:Track Based Alignment Procedures of the CBM Silicon Tracking Detec tor DTSTART;VALUE=DATE-TIME:20181025T153500Z DTEND;VALUE=DATE-TIME:20181025T155500Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1137@cern.ch DESCRIPTION:Speakers: Susovan Das (Eberhard Karls Universität Tübingen)\ nfor the CBM Collaboration — Physikalisches Institut\, Eberhard Karls Un iversität Tübingen\nThe CBM experiment at FAIR is being designed for the study of the QCD phase diagram in the region of the high baryon chemical potential at relatively moderate temperatures.

We present a complex method for preparing worki ng medium for the next generation of two-phase emission detectors planned for use in the largest international nuclear physics experiments.

At the second stage\, a massive sample of liquid xenon is purified with nanodispersed titanium generated in the liqu id by a high-voltage electric discharge between the titanium electrodes. I n the third stage\, which can run parallel to the first and second stages in time\, the internal surfaces of the detector and gas lines are cleaned by repeatedly circulating the gaseous xenon through a hot metal getter in a closed loop. At the fourth stage\, already during the operation of the d etector\, the liquid xenon is withdrawed from the filled detector\, evapor ated in a special heat exchanger\, goes through the hot metal getter\, and condensates into the detector by means of a heat exchanger.

In work some possibilities of d riving of a particle of matter in these conditions are considered. For the ir consideration the principle of ab inititio but not traditional minimiza tion of expression of action through a Lagrangian is used.\nIn this work a t first possible processes\, connected to this driving are constructed an d then Planck's quantum is used for drawing up equations of motion. Matter density in a black hole is supposed locally a constant. Radius vector of a particle is necessary to constants as well as its time. Only its impuls e and energy change. The picture\, opposite to driving of a particle in th e routine world turns out.\nTwo conditions of a particle characterized by two pairs of parameters\, time and energy (t\, E) and also a vector of a p osition and an impulse (r\, p)\, are considered. \nIf in the routine worl d at the uniform and rectilinear motion of t and r strive for infinity at constancy of E and p\, then in a black hole energy and an impulse do not g o beyond its limits. Therefore they or are tied to a point of t\, r and al ternate the phases\, or oscillate concerning it in the presence of the re flecting force\, for example\, caused by a density gradient in space (E\, p). Vectors of r and p rely collinear. \nEquations of motion are presente d in finite differences. Charts of driving at the same time form a closed circuit. Quantization of driving is made on state variables. Thus\, it tur ns out that the routine world and the world of a black hole somewhat dual each other.

An upgrade of the T2K near detec tor ND280 has a goal to reduce a systematic uncertainty in the prediction of number of events at the far detector of less than 4%. The project i ncludes the development of a new highly granular fully active scintillator neutrino detector as a neutrino target. This detector will allow us to ob tain a much better uniformity of acceptance as a function of polar angle \, to reduce the threshold for detection of charged particles\, to improve the localization of the neutrino interaction vertex\, and to effectively separate electrons from the neutrino interaction and background photons.

Recently some signals of the QGP formation were obtained in high-energy $pp$-colli sions at the Large Hadron Collider (LHC) [1]\, so the interest in the proc esses occurring in these collisions has increased.\n \nOne of the new inst ruments to study the high-energy particle collisions at the LHC was propos ed in [2] to measure the long-range correlations (LRC) between quantities observed in different (pseudo)rapidity intervals – so-called “forward ” and “backward” windows\, separated by some gap. The appearance of non-negligible values of LRC coefficients might bring important informatio n on the role of the initial stages of hadron-hadron collisions preceding the formation of the QGP.\nWe present in this report the MC-based study of long-range correlations between average transverse momentum $〈p_T 〉$ and multiplicity $n$ for particles containing strange quarks. The analysis of LRC in production of K-mesons and Lambda-hyperons in $pp$-collisions a t $\\sqrt{s}=7$ TeV is done in the framework of PYTHIA 8 event generator [ 3]. The collectivity effects in pp-collisions are taken into account in th ese MC studies by formation of a so-called “flavour rope”\, which is h adronized with a larger\, effective string tension [4\, 5]\, providing the increase of strangeness yield.\n\nThe dependencies of correlation coeffic ients $b_{n-n}$\, $b_{p_T-n}$ and $b_{p_T-p_T}$ on the gap between forward and backward pseudorapidity windows and on the width of the forward pseud orapidity window are studied. The behavior of correlation coefficients for strange particles is compared with the behavior of correlation coefficien ts for charged particles.\nIt is demonstrated that for all studied types o f particles positive $n$-$n$\, $p_T$-$n$ and $p_T$-$p_T$ correlations are observed. The correlation coefficients of strange particles in each of the considered cases are noticeably less than for charged particles. The diff erence of the behavior of the correlation coefficients of charged particle s and strange particles is discussed. The obtained results do not contradi ct the model of color string formation and fusion that might occur at the initial stage of $pp$-collision.\n\n\n 1. ALICE Collaboration.

Unambiguou s determination of the spin parity of the 13.35 MeV state is necessary to define its possible contribution to the part of the spectrum that we have previously identified as a new level in $^{12}$C with excitation energy of 13.75 MeV [7]. Initially\, we have estimated this contribution as equal t o the measured state 11.83 MeV (J$^π$ =2¯). This estimation assumed spin parity J$^π$ =2¯ of the 13.35 MeV state. However\, from our experiment was settled spin-parity of the 13.35 state is 4¯. \n\nReferences \n\n1. F. Ajzenberg-Selove\, Nucl. Phys. A 506 (1990) 1 \n\n2. P.D.

There are known expressions for the propagators of scalar\, Dir ac and massive vector fields in the presence of the constant magnetic fiel d both in the coordinate and in the momentum spaces. In general they requi re either following the tedious Fock-Schwinger procedure or first obtainin g the exact solutions of the wave equation of interest followed by summati on over the allowed quantum numbers. In this work we present a general met hod of obtaining the exact analytical solutions of the propagator equation based on the decomposition of the delta function into the sum of the Hami ltonian-like operator eigenfunctions with the subsequent integration of th e corresponding operator exponent in the proper time domain. Providing tha t parts of the operator exponent commute\, it becomes possible to decouple them from each other and apply each part separately to the delta function decomposition series. This method not just allows to straightforwardly ob tain the expression for the propagator in the momentum space as a sum over the Landau levels\, but also helps to gain insights into the propagator's anatomy\, revealing the origins of its constituent parts.\n\nhttps://indi co.particle.mephi.ru/event/22/contributions/1261/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1261/ END:VEVENT BEGIN:VEVENT SUMMARY:Cosmic ray electrons and positrons over decade with the PAMELA ex periment DTSTART;VALUE=DATE-TIME:20181026T080000Z DTEND;VALUE=DATE-TIME:20181026T081500Z DTSTAMP;VALUE=DATE-TIME:20260517T211849Z UID:indico-contribution-22-1294@cern.ch DESCRIPTION:Speakers: Vladimir Mikhailov (NRNU MEPHI)\nThe PAMELA experime nt has measured the electron and positron fluxes at Earth orbit from June 2006 till January 2016.

There are fast\, slow component s of scintillator de-excitation in such detectors and an intensity of slow component depends on the type of the detected particle.\nIn this paper\, we investigated the efficiency of several known and two new methods of dig ital pulse shape discrimination for neutrons and gamma quanta. Experimenta l data were obtained on a setup consists of a Pu-Be neutron source\, organ ic monocrystalline p-terphenyl scintillation detector and 14 bits\, 500 MH z sampling rate flash-ADC with capability to store and upload to the host computer long waveforms for further analysis. \nA comparison is made in be tween the results of using traditional and new methods for calculating the signal separation efficiency of Figure of Merit (FOM). The best known fro m the literature value of the efficiency of neutron and gamma quanta discr imination for the Pu-Be source is FOM = 1.5. We obtained the separation ef ficiency FOM = 1.77 in the scintillation detector with the p-terphenyl cry stal\, by a new method. Note also that for the known liquid scintillator B C-501A FOM≈1.\nA new method of scintillation detector pulse shape discr imination from neutrons and gamma quanta is used to detect the neutron yie ld from compact neutron generator that is created on the basis of carbon n anotubes.\n\nThe work was supported by a program of the ministry of educat ion and science of the Russian Federation for higher education establishme nts\, project №14.578.21.0192 (RFMEFI57816X0192).\n\nhttps://indico.part icle.mephi.ru/event/22/contributions/1302/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovskiy hall URL:https://indico.particle.mephi.ru/event/22/contributions/1302/ END:VEVENT END:VCALENDAR
