These measurements include cross sections measurements\, couplings measu rements\, studies of the interaction vertex structures etc. One of the mos t perspective things to study is the kinematics of the production jets\, a ssociated with the Higgs boson. It is demonstrated\, that the kinematic co rrelations of such jets can be used to distinguish different production ch annels of Higgs boson: gluon-gluon fusion (ggF) and vector boson fusion (V BF). Such separation is important due to the fact\, that possible beyond S tandard Model contributions in ggF and VBF channels lead to different phys ics effects\, which should be taken into account separately in direct BSM searches.\n\nhttps://indico.particle.mephi.ru/event/14/contributions/147/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovsky hall URL:https://indico.particle.mephi.ru/event/14/contributions/147/ END:VEVENT BEGIN:VEVENT SUMMARY:Mathematical model of dynamic detector system for detecting Cheren kov light from EAS DTSTART;VALUE=DATE-TIME:20171002T121000Z DTEND;VALUE=DATE-TIME:20171002T150000Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-232@cern.ch DESCRIPTION:Speakers: Gulmurod Shoziyoev (LPI RAS)\nCreating a new archite cture of detection system for measurements of different characteristics in astrophysics and cosmic rays detection opens new era in science.

We are interested in the special and physically umportant case when all the quadratic in cu rvature tensor (in Riemann tensor) and its constructions (Ricci tensor and scalar curvature) terms are present in the form of the square of Weyl ten sor.\n\nBy definiton\, the energy-momentum tensor of the thin shell is pro portional to Dirac's delta-function. We constructed the theory of the sphe rically symmetric thin shells for three types of gravitational theories wi th the shell.\n 1) Pure conformal (Weyl) gravity. The gravitational part of the total Lagrangian is \njust the square of the Weyl tensor.\n 2) W eyl + Einstein gravity.\n 3) Weyl + Einstein-dilaton gravity with the po ssibility of particle creation.\nThe results are compared with these in Ge neral Relativity (Israel equations).\n We considered in details the shel ls immersed in the vacuum.

Being defined in $D$-dimensional spacetime\, the gen eralized solution is also related to an arbitrary simple Lie algebra $\\ca l G$ corresponding to some hidden symmetries of the master equations of th e model. The gravitational model contains $n$ 2-forms and $l \\geq n$ scal ar fields\, where $n$ is the rank of $\\cal G$. The solution is governed b y a set of $n$ functions $H_s(z)$ obeying $n$ ordinary differential equati ons with certain boundary conditions imposed.

The polynomials $H_s(z)$\, $s = 1\,\\dots\,6$\, for the Lie algebra $E_6$ are obtained and a corresponding solution for $l = n = 6$ is presen ted. The polynomials depend on integration constants $Q_s$. They obey sym metry and duality identities. The latter ones are used in deriving asympt otic relations for solutions at large distances. The power-law asymptotic relations for $E_6$-polynomials at large $z$ are governed by integer-val ued matrix $\\nu = A^{-1} (I + P)$\, where $A^{-1}$ is the inverse Car tan matrix\, $I$ is the identity matrix and $P$ is permutation matrix\, corresponding to a generator of the $Z_2$-group of symmetry of the Dynkin diagram.

Protons\, nuclei and electrons are accelerat ed by shock waves produced by supernovae explosions. According to theory\, maximum energy of accelerated protons can be as much as 10^16 eV. For nuc lei it is Z times higher where Z is a nucleus electric charge. Other sourc es of cosmic rays cold be active dwarf stars. \nIn Galaxy there are about 4*10^11 stars and more than 90% of these stars are in the bottom part the main sequence of Gerzsprunger -Ressel diagram. Many of dwarf stars are ve ry active and produce power stellar flares. The Sun is yellow dwarf star o f G2 class. The power solar flares occur one per year and they accelera te protons up to energy about (10-20) GeV. Maximum energy released in powe r solar flares is about 10^32 ergs. \nStellar flares on active red dwarf s tars are observed more often (several times per day) and the energy relea sed during such events can have a value about 10^36 ergs. It is possible t hat the energy of accelerated protons could be as high as 10^14 eV. The ev aluations show that the stellar flares could provide the energy density in Galaxy equals to ~1 eV/cm^3. \nMany of dwarf stars are not so far from t he solar system (as the luminosities of these stars are very low they can be observed at the distances less than 50 kpc).\nNew data on spectra of g alactic protons and alfa-particles in the energy range from 50 GeV up to s everal hundreds GeV obtained in space experiments of PAMELA and AMS-02 sho w the complex energy dependence of spectral index.

It is not clea r up to now whether these symmetries have took place from the beginning or they were formed in the early Universe.\n\nOn the other hand\, the idea o f extra space almost inevitably leads to charge non conservation. Indeed i n the framework of multidimensional gravity observed low energy symmetries are the consequences of isometries of extra space. It is assumed that the re are no any Killing vectors of a nucleated manifold in the very beginnin g. The first stage of an extra space formation consists of its symmetrizat ion. Hence\, there are no conserved charges at this stage. Charge conserva tion appears much later when the extra space geometry acquires appropriate Killing vectors. The situation is similar to those concerning the problem of baryon asymmetry. \n\nIn the present paper we consider a mechanism of the baryon asymmetry generation accompanied by symmetrization of extra spa ce. It is assumed that the baryon symmetry (asymmetry) is the consequence of symmetry (asymmetry) of extra space. The corresponding symmetry of the theory is restored during the process of evolution at later stages.\n\nhtt ps://indico.particle.mephi.ru/event/14/contributions/195/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovsky hall URL:https://indico.particle.mephi.ru/event/14/contributions/195/ END:VEVENT BEGIN:VEVENT SUMMARY:Realistic simulation of BM@N GEM detectors: model implementation a nd testing DTSTART;VALUE=DATE-TIME:20171002T121000Z DTEND;VALUE=DATE-TIME:20171002T150000Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-194@cern.ch DESCRIPTION:Speakers: Tatiana Mamontova (NRNU MEPhI)\nThe Lorentz shift of electrons in a magnetic field is taken into account with simulating the r esponse of a GEM detector for the BM@N experiment.

According to this wide range of usage of GEM like detectors and their developments\, improving the robustness and gain level of them attract a lot of interests. The aim of this paper is to desi gn and to manufacture the first triplet RETGEM nuclear detector by using a rtificial intelligent systems. Adding the layers of the detector\, from si ngle RETGEM to triplet one and choosing the proper range of parameters red uces the electrical discharge probability and so we would achieve the high er gain levels. We use the Printed Circuit Boards (PCB) as the basic part of RETGEM layers and then cover them using a thin layer of graphite as a r esistive conductor. In the next step\, the container bulk and electrical p arts have been manufactured. The electrical part of the detector is a Char ge Sensitive Amplifier (CSA)\, which it amplifies the results and filters the noises. The measurements by the manufactured RETGEM nuclear detectors shows that the triplet RETGEM filled by mixture gasses of Ar-CO2 with 80-2 0 percentage can achieve to the gain levels up to 10 million while the gai n level of a single RETGEM in the same condition rises up to 0.1 million.

For most EAS experiments the re gion lower than 1000 TeV is below threshold.

The shape of LDF is very sensitive to the depth of EAS maximum and as a result to the sort of primary particles. In this report\, we developed a method and studied the possibility to sep arate heavy and light groups of nuclei using the 'knee-like' fitting funct ions of LDF. We revealed which parameters of fitting functions are the mos t sensitive to the sort of primary nuclei and showed that the additional f luctuations caused by the procedure of measurement (measurement fluctuatio n) should be known in detail.

Natural width of this line of $\\Gamma_{natur} = 1. 3\\cdot10^{-19}$ eV\, which is nearly $85$ times more than the the investi gated silver[1].\n\nIn the case of studying the gamma resonances of the lo ng-lived isomers with the measurement of the shape resonance by scanning o f the peak of resonance absorption of gamma-line Doppler shift method is v ery difficult\, because it would take the device generates the speed of th e source relative to the absorber $\\propto10^{-12}-10^{-13}$ $cm/sec$ tha t cannot a mechanical device.\n\nIf the gamma quantum moves in the gravita tional field and the point of emission and absorption have the height diff erence $\\Delta h$ \, it will have a shift of energy at the point of absor ption relative to its energy at the point of emission $\\Delta E_{\\gamma} = E_{\\gamma} g \\Delta H / c^2$ \, where $E_{\\gamma}$ - is the energy o f the gamma quantum at the point of emission\, $g$ - is the gravitational acceleration\, $\\Delta h$ - is the difference between points of emissio n and absorption\, c - is the speed of light.

The second direction is tied with the measurements by а solid scintillator d etector DANSS (Detector of Anti-Neutrino based on Solid Scintillator) desi gned for remote on-line diagnostics of nuclear reactor parameters and sear ch for short range neutrino oscillations. It is now installed at the Kalin in Nuclear Power Plant.

Mass ive\, rotation-dominated discs are already in place at z~2\, but they are dynamically hotter than spiral galaxies in the local Universe. Although s everal plausible mechanisms for this elevated velocity dispersion (e.g. st ar formation feedback\, elevated gas supply\, or more frequent galaxy inte ractions) have been proposed\, the fundamental driver of the velocity disp ersion enhancement at high redshift remains unclear. We investigate the or igin of this kinematic evolution using a suite of cosmological simulations from the FIRE (Feedback In Realistic Environments) project. These simulat ions reproduce the observed trends between intrinsic velocity dispersion \ , SFR\, and z\, but the intrinsic velocity dispersion traced by the star-f orming gas in the simulated galaxies is systematically lower than the obse rved values. \nIn both the observed and simulated galaxies\, the velocity dispersion is positively correlated with SFR. The velocity dispersion incr eases with redshift out to z~1 and then flattens beyond that. In the FIRE simulations\, the velocity dispersion can vary significantly on timescales of less than 100 Myr. These variations closely mirror the time evolution of the SFR and gas inflow rate. By cross-correlating pairs of velocity dis persion\, gas inflow rate\, and SFR\, we show that the increased gas inflo w leads to subsequent enhanced star formation\, and enhancements in the ve locity dispersion tend to temporally coincide with increases in gas inflow rate and SFR.\n\nhttps://indico.particle.mephi.ru/event/14/contributions/ 146/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovsky hall URL:https://indico.particle.mephi.ru/event/14/contributions/146/ END:VEVENT BEGIN:VEVENT SUMMARY:Tests of the Electromagnetic Calorimeter for HADES Experiment at G SI DTSTART;VALUE=DATE-TIME:20171002T121000Z DTEND;VALUE=DATE-TIME:20171002T150000Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-145@cern.ch DESCRIPTION:Speakers: Andrey reshetin (Institute for Nuclear Research\, Ru ssian Academy of Sciences\, 117312 Moscow\, Russia)\nMeasurements of mass spectra of dilepton pairs in the HADES experiment in the energy domain of SIS18 and SIS100 (GSI\, Germany) are very important to study the excitatio n function of the virtual photon radiation from dense nuclear matter.

It turned out that this state has the same radius as the mirror state 1/2 +\, 3.09 M eV in 13C\, in spite of the fact that one of them lies under the threshold of neutron emission\, and the second one lies above the threshold of prot on emission. This observation allows us to take the next step and try to a pply this approach to measure the radii of isobar - analog states.\nThe in creased radii in the first excited states of the 6He-6Li-6B triplet\, whic h may also have a halo structure\, are not excluded.\nThe neutron halo in 6He is well known. A proton-neutron halo is predicted in the excited state of 0+\, 3.56 MeV in 6Li\, which lies only 137 keV below the 6Li -> 4He + p + n threshold. Its radius is not known\, but it is predicted to be about 0.25 fm larger than the 6He radius. One can expect the appearance of a tw o-proton halo in the ground state of 6Be.\nAs a first step\, we analyzed t he published differential cross sections for inelastic scattering of 3He + 6Li with the excitation of the 2.19 MeV\, 3+ state at energies 34 and 72 MeV and 3.56 MeV\, 0+state at energies 24.6 and 27 MeV.\nProbably the stat e 0+\, 3.56 MeV has the same radius as its "Borromean" isobar analogue 6He . The increase in the radius predicted in [1] because of the more extended wave function p - n\, apparently\, does not take place. Thus\, the transi tion from the Borromean to the tango structure does not change the radius of the state. We recall that the spatial structure of the 6He nucleus was predicted to be quite complex\, in which correlations of two types appeare d: "cigar" and "dineutron." The question arises: does the structure of the state change so much when passing from 6He to the isobar analog in 6Li\, which requires the introduction of a special kind of tango-halo.\n[1] K.

The measurem ents were carried out at the cyclotron of the University of Jyvaskyla (Fin land) using Large Scattering Chamber (LSC). The idea of the work was to se arch for two states with the expected neutron halo\, 1¯ and 2¯.\nDiffere ntial cross sections with excitation of 12B states\, including abovementio ned states\, were observed.\nThe preliminary calculations on halo radii by the method of asymptotic normalization coefficients for the 2¯ and 1¯ s tates gave following values: 5.9 fm and 7.7 fm\, which is much larger than the radius of the valence neutron in the ground state. This confirms the presence of a neutron halo in these states\, which are in a discrete spect rum.\nAn unexpected result was obtained for the 3¯\, 3.39 MeV state\, whi ch is in continium 19 keV above the decay threshold 12B → 11B + n\, esti mation for its halo radius is ~ 6.5 fm.

We compare the results of the interacting shell-model [1]\, continuum quasiparticle random phase ap proximation DF+CQRPA based on the Fayans functional [2]\, relativistic Har try-Bogolubov QRPA [3]\, and Finite Amplitude Method [4] based on the Skyr me functional. All the frameworks include both the allowed Gamow–Teller and first-forbidden beta decays on the same microscopic footing. The beta- decay half-lives and delayed multi- neutron emission branchings are confro nted for the “reference nuclides” near the major neutron shells-closur es at N=50\, 82. An emphasis is made on the share of the first-forbidden d ecays in the total rates. The results are also checked against the known h indrance factors and for consistency with available experimental decay sch emes. A detailed beta decay study is performed for the K\, Ca\, Sc nuclide s near the new neutron sub-shells at N=32\, 34. In a view of recently dis covered anomalous nuclear radii in heavy Ca isotopes [5]\, a special atten tion is payed to possible constraints imposed by the beta-decay strength f unctions\, half-lives and delayed multi-neutron emission branchings on the strength of quasiparticle-phonon coupling. Taking an account of this effe ct has been found to be of prime importance for solving the problem of “ Ca anomaly” [6].\n\n[1] Q. Zhi\, E. Caurier\, J. Cuenca-Garc’ia\, K. L anganke\, G.

Therefore\, gamma-ray astronomy plays an important role\, since ga mma-rays occur simultaneously with CR\, but do not deflect in magnetic fie lds and can be relatively easily detected in the ground-based setups. Gamm a astronomy made a powerful breakthrough in the GeV and TeV energy ranges over the past decade. However\, important questions remain open\, such as the observation of PeVatrons – CR sources in the Galaxy\, where gamma qu anta with energies more than 100 TeV may be generated. This subject is ess ential for the CR acceleration mechanism explanation.\n\nAn experimental s etup of a new generation is created in the TAIGA collaboration. This is a complex of detectors of various types designed to measure extensive air sh owers (EAS)\, and is located in the Tunka valley\, 50 km from the Lake Bai kal. In addition to the muon and wide-angle Cherenkov optical detectors Hi SCORE\, it is proposed to construct up to 16 IACTs (Imaging Atmospheric Ch erenkov Telescope). The IACT\, which measures EAS together with other dete ctors\, will improve the sensitivity of all complex of detectors.\n\nThe f irst IACT has been operating in the test mode since 2016.

A nu mber of successful experiments arranged by ZEPLIN\, XENON\, LUX and PandaX collaborations with LXe emission detectors during 10 years period reduced allowed region of existence for WIMPs with mass of 40-50 GeV/c2 from 8.8$ \\times$10-44cm2 (reported by XENON-10 collaboration in 2006) down to 1.1$ \\times$10-46cm2 (reported by LUX collaboration at the end of 2016). \nDet ector LZ of the second generation (G2) will be installed at Davis’ cage of the Homestake mine by joint collaboration of former LUX and ZEPLIN expe riments and will use 6 ton LXe active mass emission detector in order to r each a sensitivity below 10-47 cm2 for spin-independent WIMP-nucleon inter actions. With the increasing detector mass and sensitivity\, solar neutrin o interactions become an irreducible source of background for WIMP search experiments. Multi-ton active mass WIMP detectors of the upcoming G3 gener ation shall become\, even with naturally occurring isotope abundances\, se nsitive to double-beta decay at the modern level of sensitivity and solar neutrinos interactions via elastic coherent scattering off xenon nuclei. D etectors of G3 generation such as DarkSide-20k can achieve spin-independen t cross sections for WIMPs as low as ~ 7.4$\\times$10-48cm2 (6.9$\\times$1 0-47cm2) for WIMPs of 1TeV/c2 (10TeV/c2 ) mass. \nThe RED-100 detector re cently constructed at NRNU MEPhI has been constructed for the first observ ation of the elastic coherent electron neutrino scattering off xenon nucle i when the detector is installed practically on the Earth's surface in vic inity to low energy neutrino source such as NPP nuclear reactor or Spallat ion Neutron Source. \nThe LBNO (Long Baseline Neutrino Observatory) experi ment intends to use large Liquid Argon (LAr) double-phase time projection chamber (DLAr TPC) as one of the detectors. The consortium at CERN is now active in the construction of a large demonstrator LBNO-DEMO DLAr TPC of 3 x3x1 m3 active volume.\nThus the detector technology invented at MEPhI alm ost 50 years has demonstrated a great potential to be used in a variety of fundamental research programs.\n\nhttps://indico.particle.mephi.ru/event/ 14/contributions/113/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovsky hall URL:https://indico.particle.mephi.ru/event/14/contributions/113/ END:VEVENT BEGIN:VEVENT SUMMARY:COHERENT Experiment: CENNS-10 detector DTSTART;VALUE=DATE-TIME:20171004T061500Z DTEND;VALUE=DATE-TIME:20171004T063000Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-112@cern.ch DESCRIPTION:Speakers: Alexander Kumpan (National Research Nuclear Universi ty MEPhI)\nCENNS-10 is a single-phase liquid Ar detector used for detectio n and studying of a coherent elastic neutrino-nucleus scattering (CEvNS) o ff Ar nuclei within the COHERENT Experiment.

One of the main problems is the correlated background from fast neutrons caused by space radiation . Attempts to suppress the background of fast neutrons by sectioning the d etector have given the required result. The relation of effect/background has improved from 0.3 to 0.6. As a result\, measurements of the difference in the counting rate of neutrino-like events (reactor ON-reactor OFF) for a full-scale detector have been obtained as dependence on distance from t he reactor center. Besides\, the spectrum of prompt signals of neutrino-li ke events has been presented. The fit of experimental dependence with the law $1/L^{2}$ \, however\, does not give an absolutely satisfactory result . The goodness of that fit is a little more than 10%\, i.e. the confidence level is about 90% in deviation from the law $1/L^{2} (1.64\\sigma)$. The similar situation arises in the analysis of spectrum dependence of prompt signals\, which is also 90% of confidence level. Of course\, the joint de viation\, demanding identical parameters $\\Delta m_{14}^{2} =0.7 \\div 0. 8~eV ^{2}$ and $sin^{2}(2\\theta_{14})$=$0.10\\div0.15$\, increases the c onfidence level up to about 95% $(2\\sigma)$. But it is still not enough f or making statements on observation of the phenomenon\, especially\, such an important one as oscillations in a sterile state. At last\, it is also impossible now to exclude possibility of influence of systematic errors on the final experimental result. Therefore\, in future we would like to con centrate efforts on increase in accuracy of the experiment and control of possible systematic errors.\n\nhttps://indico.particle.mephi.ru/event/14/c ontributions/110/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovsky hall URL:https://indico.particle.mephi.ru/event/14/contributions/110/ END:VEVENT BEGIN:VEVENT SUMMARY:Active Muon Shield for the SHiP Experiment at CERN DTSTART;VALUE=DATE-TIME:20171005T142500Z DTEND;VALUE=DATE-TIME:20171005T144000Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-109@cern.ch DESCRIPTION:Speakers: Artem Filatov (Higher School of Economics\, Yandex S chool of Data Analysis)\nThe SHiP experiment is designed to search for ver y weakly interacting particles beyond the Standard Model which are produce d in a 400 GeV/c proton beam dump at the CERN SPS.

In addition an attention has been devoted to effects of var ying the ratio between the proton $Z$ and neutron $N$ numbers on different nuclear structure characteristics of nuclei deviated from their valley of $\\beta$-stability. One of the phenomena associated with the change in $N /Z$ ratios is the pygmy dipole resonance (PDR). The PDR leads to the enhan cement of dipole strength below the region of the isovector giant dipole r esonance. The structure and dynamics of the PDR is one of the hot topics i n nuclear physics. There is a special structure of the PDR which appears a s a new collective motion in neutron-rich nuclei [2]. The other reason is the role of the PDR in nucleosynthesis. The PDR also induces noticeable ef fects on $(\\gamma\,n)$ cross section and on the r- process [3].\n\nThe qu asiparticle random phase approximation (QRPA) with a self- consistent mean -field derived from Skyrme energy density functionals (EDF) is one of the most successful methods for studying the low-energy dipole strength\, see e.g.\, Ref. [2]. Due to the anharmonicity of vibrations there is a couplin g between one- phonon and more complex states. The main difficulty is that the complexity of calculations beyond standard QRPA increases rapidly wit h the size of the configuration space\, and one has to work within limited spaces. Using a finite rank separable approximation for the residual part icle-hole interaction derived from the Skyrme forces one can overcome this numerical problem [4-6]. As an illustration\, we study the properties of the low-lying dipole states in the even-even nuclei $^{40-58}$Ca. Using th e same set of the EDF parameters we describe available experimental data f or $^{40\,44\,48}$Ca and give the prediction for $^{50-58}$Ca [7]. In part icular\, there is an impact of the coupling between one- and two-phonon st ates on low-energy $E1$ strength of $^{40\,44\,48}$Ca. We predict a strong increase of the summed $E1$ strength below 10 MeV\, with increasing neutr on number from $^{48}$Ca.\n\n[1] D. Savran\, T. Aumann\, A. Zilges\, Prog. Part. Nucl.

To solve thi s problem it is convenient to use passive detector's that have a number of advantages: they are cheap\, compact\, does not consume electric power\, maintenance-free during exposure and allows to evaluate large number of ph ysical quantities. \n\nIn the first two-year phase of the on-going **Proje ct** LET spectra\, absorbed dose and dose equivalent rates are measured in the direct vicinity of the samples in three different modules of the *Rus sian segment* by applying sets of passive detector packages. The sets of s pace radiation detectors comprising of *Thermo-luminescent Dosimeters* mad e of LiF:Mg\,Ti (MTS-6\, MTS-7\, DTG-4) materials and *Solid State Nuclear Track Detectors* made of PADC (polyallyl-diglycol-carbonate) are recovere d in 4 consecutive sessions after **0.5**\, **1**\, **1.5** and **2** year exposure. The contribution of secondary neutrons and heavy nuclear fragme nts to the total space radiation doses is also assessed with the use of an extensive analysis. The space radiation data acquired in the experiment a llowed observing the dose variations on the decline of the 24th Solar Cycl e.\n\nAveraged measurements from the first session (Nov 2014 - Jun 2015) r esulted in more than **2.5** times higher total dose rate in the *Pirs* do cking module than in the *Service* module. This difference might be explai ned by the much weaker shielding of the *Pirs* module\, thus the greater c ontribution of high-LET components to the dose rate and the easier penetra tion of low-LET particles. \n\nThis report presents detailed analysis of s pace radiation data obtained with passive detectors during the 1st Phase o f the **Project** in 2014-2016 by Russian and Hungarian research groups.\n \nhttps://indico.particle.mephi.ru/event/14/contributions/96/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovsky hall URL:https://indico.particle.mephi.ru/event/14/contributions/96/ END:VEVENT BEGIN:VEVENT SUMMARY:Digital systems by CAEN for multiparameter analysis in physical ap plications DTSTART;VALUE=DATE-TIME:20171004T145000Z DTEND;VALUE=DATE-TIME:20171004T150500Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-95@cern.ch DESCRIPTION:Speakers: Ivan Bredikhin (GammaTECH)\nКомпания CAEN я вляется одним из безусловных лидеров ры нка цифровой электроники и является еди нственной компанией в мире\, предоставля ющей полный спектр высоковольтных и низ ковольтных источников питания\, а также различных модулей сбора данных\, соответ ствующих всем стандартам IEEE.

Above $100$ TeV calculated spectr a of muon neutrinos show the apparent dependence on the spectrum and compo sition of primary cosmic rays around to the knee. At energies above $1$ Pe V additional uncertainties appear due to production of charmed particles a nd also from the high-energy models of primary cosmic ray spectra which im print on the prompt neutrino flux.\n\nBasing on this calculation we study the influence of hadron-nuclear interactions on the neutrino-to-antineutri no flux ratios $\\nu_{e} / \\bar \\nu_{e}$\, $\\nu_{\\mu} / \\bar \\nu_{\ \mu}$ and the neutrino flavor ratio $(\\nu_{\\mu}+\\bar \\nu_{\\mu)} / (\\ nu_{e}+\\bar \\nu_{e})$. These neutrino flux characteristics are sensitive to $\\pi^{+} / \\pi^{-}$\, $K^{+}/K^{-}$ and $\\pi/K$ ratios\, depending on cross-sections of the meson production in $hA$-collisions. The cosmic-r ay composition due to $p/n$ ratio also affects the hadronic cascade evolut ion and neutrino ratios.\n\nThe comparison of predicted neutrino spectra w ith the latest exprimental data\njustifies reliability the performed compu tation which correctly describes in whole\nthe atmosheric neutrino product ion. Atmosperic muon neutrino spectra\, calculated with use of Kimel-Mok hov\, SIBYLL 2.1 and EPOS LHC hadronic models\, are consistent with the e xperimental results. At energies $1−500$ TeV curves calculated for these modeles combined with Hillas-Gaisser cosmic-ray spectrum\, are close to the best fit of IceCube.\nCalculations of the flavor ratio using SIBYLL 2. 1 and QGSJET ll agree well with only experimental point at 1.7 TeV derive d in IceCube experiment.\n\nhttps://indico.particle.mephi.ru/event/14/cont ributions/87/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovsky hall URL:https://indico.particle.mephi.ru/event/14/contributions/87/ END:VEVENT BEGIN:VEVENT SUMMARY:RED-100 experiment : current status DTSTART;VALUE=DATE-TIME:20171002T121000Z DTEND;VALUE=DATE-TIME:20171002T150000Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-86@cern.ch DESCRIPTION:Speakers: Alexander Khromov (NRNU MEPhI)\nThe current status o f the RED-100 experiment is presented.

As the acuracy of this approximation is rather high we can use it to test various models of hadronic interactions with the help of atmospheric muon energy spectra. The atmospheric vertical muon energy spectra have been ca lcullated in terms of the EPOS LHC\, QGSJET01\, QGSJETII-03 and QGSJETII-0 4 models in the energy range $10^{2} \\div 10^{5}$ GeV with help of the CO RSIKA package and this new approximation of the primary nucleon spectrum. Results of calculations have been compared with the muon spectra observed by collaborations L3+Cosmic\, LVD and MACRO. The analysis has shown that a ll models predict approximately two times lower intensity of the muon ener gy spectra. As these muons are products of decays of the most energetic $\ \pi^{\\pm}$ and $K^{\\pm}$ mesons in the atmosphere\, we can conclude that production of these $\\pi^{\\pm}$ and $K^{\\pm}$ mesons is underestimated by EPOS LHC\, QGSJET01\, QGSJETII-03 and QGSJETII-04 models.\n\nhttps://i ndico.particle.mephi.ru/event/14/contributions/79/ LOCATION:Hotel Intourist Kolomenskoye 4* Moskvorechye-2 hall URL:https://indico.particle.mephi.ru/event/14/contributions/79/ END:VEVENT BEGIN:VEVENT SUMMARY:Quarkonia measurements in 5 TeV heavy-ion collisions with the ATLA S detector DTSTART;VALUE=DATE-TIME:20171003T142500Z DTEND;VALUE=DATE-TIME:20171003T144500Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-78@cern.ch DESCRIPTION:Speakers: Nikita Smirnov (NRNU MEPhI)\nThe in-medium suppressi on of heavy quarkonia production in heavy-ion collisions\, with respect to proton-proton collisions\, serves as a sensitive probe for studying the Q GP.

A fundamental constant is the average speed of light back and forth. The independence of this observed value of the choice of inert ial reference systems supported by the Michelson-Morley experiment.Then Jo hn A Winnie in 1970\, formulated a generalization of the special theory of relativity to the case of generalized synchronization Reichenbach. Curren tly\, there is discussion about the consistency with the physical experime nts of Reichenbach's thesis of the conventionality of simultaneity spatial ly separated clocks.\nWithout entering into this discussion about the phys ical reality according to Reichenbach's thesis in this paper\, we propose the possibility of using non-standard synchronization in the relativistic -invariant integral formulation of the laws of conservation of charge\, th e energy - momentum\, and other conserved quantities.\nFor two inertial re ference systems\, the relativity of simultaneity phonological paradigmatic events.Richard Feynman in his Nobel lecture gave an example of the depart ure of electron-positron pair from the two ends of the rod of finite lengt h. On the basis of the fact of the relativity of simultaneity of these two events\, he concluded that the local law of conservation of electric char ge for non-point objects.\nAt first\, for example\, in a textbook of Theor etical Physics Landau-Lifshitz theory of special relativity is formulated in four-dimensional space-time of Minkowski. The equations of the dynamics of the material point is a relativistic generalization of Newton's laws c ontain as a time parameter interval proportional to the proper time of the moving material point\, which does not depend on clock synchronization. B y synchronizing the clocks do not depend on the energy\, momentum\, and ot her conserved quantities.\nConsider the insular system of mutually motionl ess particles. The law of conservation of charge for this system in differ ential form is expressed as the vanishing of the divergence of a four-vect or volumetric current density. To calculate the integral formulation of th e integral over the four-volume tube world lines of particles insular syst em\, forming a four-cylinder. This cylinder ends of two perpendicular to t he world lines of the surfaces of simultaneous events belonging to the two points in time of the observer in his own frame of reference insular syst em. The lateral surface of the cylinder tends to spatial infinity\, where the charges are zero. In the four-dimensional Gauss theorem the volume int egral is converted to the integral over a closed surface\, decaying on the lateral surface and two bases. The result is an equality of two integrals over the three-dimensional hypersurfaces for different points in time. Th is means consistency\, i.e the conservation of the total charge insular sy stem. All the above corresponds to the integrated treatment of conservatio n laws in the course of Landau-Lifshitz. \nIf we move to the laboratory re ference system relative to which the insular system is moving inertially\, then the hypersurface of simultaneity used in the insular system\, cease to be orthogonal to the temporal axis of the laboratory system. Because of the relativity of simultaneity there is an unequal one second parameter R eichenbach\, the speed of light is a fundamental constant is only an avera ge. The hypersurfaces of simultaneity in the four-dimensional Minkowski sp ace are invariant geometric objects. In the area of the relativity of simu ltaneity\, you can choose any hypersurface\, while the numerical values of the integrals of the remaining quantities do not depend on the choice of hypersurfaces of simultaneity. Thus\, if you declare a custom setting for the Reichenbach physically invalid\, it returns solemnly to ensure the cov ariant integral formulation of the conservation laws of physical quantitie s.\n\nhttps://indico.particle.mephi.ru/event/14/contributions/70/ LOCATION:Hotel Intourist Kolomenskoye 4* Moskvorechye-2 hall URL:https://indico.particle.mephi.ru/event/14/contributions/70/ END:VEVENT BEGIN:VEVENT SUMMARY:GEM tracking system of the BM@N experiment DTSTART;VALUE=DATE-TIME:20171002T121000Z DTEND;VALUE=DATE-TIME:20171002T150000Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-69@cern.ch DESCRIPTION:Speakers: Elena Kulish (JINR)\nBM@N (Baryonic Matter at the Nu clotron) is the fixed target experiment aimed to study nuclear matter in t he relativistic heavy ion collisions at the Nuclotron accelerator in JINR.

The transmission method based on registration of energy loss in the material of ∆E detector (Si target) as well as registration of n-γ radiation by the 4π spectrometer was used. The interesting results were the unusual wi de enhancement of total cross section for 9Li+28Si reaction in the energy range ~10-30 A·MeV as compared with 6\,7Li+28Si reactions. The similar we aker behavior was found for 6He+28Si reaction as compared with 4He+28Si re action. The microscopic approach based on the numeric solution of the time -dependent Schrödinger equation for the external neutrons of weakly bound projectile nuclei combined with the optical model is proposed for descrip tion of the observed effects. These are explained by the rearrangement of external neutrons and thus the increase of neutron probability density in the region between the two nuclei during their collision in the energy ran ge ~10-30 A·MeV. The corrections to the nucleus-nucleus potential associa ted with the rearrangement of external neutrons were determined by integra tion of their probability density over the region between the two nuclei.

The nature of neutron impulses can be both astrophysical and artificial origin. In as trophysical conditions\, the formation of heavy nuclei occur at multiple n eutron capturing process in rapid r-process [1]\, for example\, at superno va explosions. In terrestrial conditions such processes are take places in nuclear/thermonuclear explosions [2]. The explosive process of artificial origin are differed from astrophysical ones by small duration time (t 40 0%\, or recent calculations [7] with δE([7]) = 180 %. For “Par” exper iment we had obtained δE(ABM) = 33% and for Dorn and Hoff [8] δE([8]) = 76 %. For “Barbel” experiment δE(ABM) = 33% and compare to Bell [2] δE([2]) = 54%. So it is possible to conclude that the authors ABM-model [5] allows to obtain better results in simulations of transuranium isotope s under conditions of nuclear explosions.\nThe calculations include the pr ocesses of delayed fission (DF) and the emission of delayed neutrons (DN)\ , which determine the "losing factor" – the total loss of isotope concen tration in the isobaric chains. The DF and DN probabilities were calculate d in the microscopic theory of finite Fermi systems. Thus\, it was possibl e to describe the even-odd anomaly in the distribution of concentrations N (A) in the mass number region A = 251 – 257. It is shown qualitatively a lso that the odd-even anomaly may be explained mainly by DF of very neutro n-rich uranium isotopes.\nThe work is supported by the Russian RFBR grant 16-02-00228 and RSF project 16-12-10161.\n\n1.

The main purpose of the FHCAL is to provide an experimental measurement of a heavy-ion collision centrality and orientation of its rea ction plane. FHCAL consists of two identical arms placed at the left/right sides from the beam collision point. This is a modular lead-scintillator compensating calorimeter designed to measure the transverse energy distrib ution of the projectile nuclei fragments (spectators) and forward going pa rticles produced close to the beam rapidity. The FHCal has a large central beam hole. Therefore\, in the peripheral collisions the most of heavy fra gment escape into this beam hole. Nevertheless\, the detection of the tran sverse energy distribution in inner and outer parts of the calorimeter all ows the reconstruction of the collision centrality. The longitudinal seg mentation of FHCal modules into 7 sections makes possible to identify the particle types (electrons\, hadrons and muons) depending on the longitudin al profile of the energy losses in the modules. This identification abili ty is used for the quality check and the calibration of the FHCal modules with minimum ionizing particles.\nThe construction of the FHCal modules\, the methods of the energy calibration with cosmic muons and the parameters of the modules are discussed.\n\nhttps://indico.particle.mephi.ru/event/1 4/contributions/40/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovsky hall URL:https://indico.particle.mephi.ru/event/14/contributions/40/ END:VEVENT BEGIN:VEVENT SUMMARY:On possible injection scheme for FCC-ee DTSTART;VALUE=DATE-TIME:20171002T121000Z DTEND;VALUE=DATE-TIME:20171002T150000Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-39@cern.ch DESCRIPTION:Speakers: Helen Barminova (NRNU MEPhI)\nPossible variant of th e conventional injection scheme for 175 GeV/beam operation mode of FCC-ee collider is discussed.

Some of the recent experiments focus on the co incidence measurement of the prompt gamma-rays emitted in the interaction of heavy ions and atmosphere. \n A number of simulation codes have been de veloped for prediction of cosmic ray reactions. However\, very few can sim ulate event-by-event prompt gamma-ray emission because it is necessary to determine the isotopic species produced in each reaction and to calculate the internal transition intensity between discrete levels based on the nuc lear structure data. \n The excitation energy of heavy ion fragments is pr edominantly emitted as prompt gamma-rays. Therefore the gamma-rays from en ergetic projectile fragments are Lorentz-boosted and observed as energetic gamma-rays in the laboratory frame. Because the Lorentz gamma-factor of e ach fragment can be large\, the gamma-rays reach GeV range. \n In order to consistently calculate the fragmentation reactions leading to gamma-ray e mission\, reactions models were revised and implemented to the general-pur pose radiation transport code PHITS. In this work\, the non-equilibrium ph ase of the projectile-target nuclear reaction\, the equilibrium decay phas e\, and the gamma de-excitation phase are simulated by the Jaeri Quantum M olecular Dynamics model (JQMD)\, the generalized evaporation model (GEM)\, and ENSDF-Based Isomeric Transition/isomEr production Model (EBITEM)\, re spectively. \n Recently\, JQMD was revised to precisely calculate peripher al collisions in addition to central collisions. EBITEM is a gamma-decay r eaction model\, which uses the nuclear structure data taken from ENSDF and the angular momenta of the residual nuclei after the statistical decay. B ecause all these models are event generators\, secondary particle emission was calculated in event-by-event basis.

The hypothesis of virtual gravitational dipoles permits to consider the Standard Model matter (i.e. matter compose d from quarks and leptons interacting through the exchange of gauge bosons ) as the only matter-energy content of the Universe. The phenomena usually attributed to hypothetical dark matter\, may be considered as a consequen ce of the local gravitational polarization of the quantum vacuum by the im mersed baryonic matter\; apparently\, the galactic halo of dark matter can be replaced by the halo of the polarized quantum vacuum. Globally quantum vacuum may be considered as a cosmological fluid which during expansion o f the Universe converts from a fluid with negative pressure\, allowing an accelerated expansion of the Universe\, to a fluid with zero pressure (phy sically it means the end of the accelerated expansion). In addition\, as a consequence of hypothesis of virtual gravitational dipoles together with the gravitational version of the Schwinger mechanism\, we may live in a cy clic universe with cycles alternatively dominated by matter and antimatter . At least mathematically there is no the initial singularity\, there is n o need for the cosmic inflation and there is an amusing explanation of the matter-antimatter asymmetry in the universe: our universe is dominated by matter because the previous cycle was dominated by antimatter (and the ne xt cycle would be dominated by antimatter again).\n\nhttps://indico.partic le.mephi.ru/event/14/contributions/30/ LOCATION:Hotel Intourist Kolomenskoye 4* Moskvorechye-1 hall URL:https://indico.particle.mephi.ru/event/14/contributions/30/ END:VEVENT BEGIN:VEVENT SUMMARY:Status of COHERENT:CsI[Na] experiment at SNS DTSTART;VALUE=DATE-TIME:20171004T123000Z DTEND;VALUE=DATE-TIME:20171004T124500Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-29@cern.ch DESCRIPTION:Speakers: Alexey Konovalov (MEPhI/ITEP)\nThe COHERENT collabor ation aims to observe coherent elastic neutrino nuclear scattering\n(CEvNS ) using several detector options including Ge\, Ar\, NaI and CsI[Na].

This is due to the fact that the quantum-corrected metric contains some combinations of the stress -energy tensor having the meaning of the energy measured by a free-falling observer that potentially may diverge near the extremal horizon. However\ , numerical calculations showed that such divergencies do not occur for ma ssless fields in the Reissner-Nordstrom background [1].

One can find in the literature the opinion that the Wheeler – DeWitt equation is even more fundamental than the basic equation of quantum theory\, the Schrödinger equation [1]. We still should remember that we are in the situation when no observation al data can confirm or reject a fundamental status of the Wheeler – DeWi tt equation\, so we can give just indirect arguments in favor of or agains t it\, grounded on mathematical consistency and physical relevance. I shal l present the analysis of the situation and comparison of the standard Whe eler – DeWitt approach with the extended phase space approach to quantiz ation of gravity [2]. In my analysis I suppose\, firstly\, that the future quantum theory of gravity must be applicable to all phenomena from the ea rly Universe to quantum effects in strong gravitational fields\, in the la tter case the state of the observer (a choice of a reference frame) may ap pear to be significant. Secondly\, I suppose that the equation for the wav e function of the Universe must not be postulated but derived by means of a mathematically consistent procedure\, which exists in path integral quan tization. Thirdly\, when applying this procedure to any gravitating system \, one should take into account features of gravity\, namely\, non-trivial spacetime topology and possible absence of asymptotic states. The Schröd inger equation has been derived early for cosmological models with a finit e number of degrees of freedom [3]\, and just recently it has been found f or a spherically symmetric model which is a simplest model with an infinit e number of degrees of freedom. The structure of the Schrödinger equation and its general solution appears to be very similar in these cases. The o btained results give grounds to say that the Schrödinger equation retains its fundamental meaning in constructing quantum theory of gravity.\n\n[1] C. Rovelli\, *Class.

The femtoscopic studies of baryon-(anti-)baryon\, and kaon pairs provides an unique opportunity to extract the strong interaction par ameters and cross-sections of these particle pairs.\n\nhttps://indico.part icle.mephi.ru/event/14/contributions/14/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovsky hall URL:https://indico.particle.mephi.ru/event/14/contributions/14/ END:VEVENT BEGIN:VEVENT SUMMARY:Constrains on the model of dark matter with Coulomb-like interacti on explaining positron anomaly DTSTART;VALUE=DATE-TIME:20171002T121000Z DTEND;VALUE=DATE-TIME:20171002T150000Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-13@cern.ch DESCRIPTION:Speakers: Ekaterina Esipova (NRNU MEPhi)\nIt is often supposed that dark matter possesses own interaction in particular like Coulomb. It leads to inhacement of annihilation in Galaxy what helps to explain cosmi c ray anomalies\, e.g. positrons. We put constrains on such model coming f rom CMB\, hot dark matter abundance and also outline parametr region where classical approach is relevant for description of annihilation through bo und state formation. The given constrains are applied to dark disk model.\ n\nhttps://indico.particle.mephi.ru/event/14/contributions/13/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovsky hall URL:https://indico.particle.mephi.ru/event/14/contributions/13/ END:VEVENT BEGIN:VEVENT SUMMARY:Detection of tensor and scalar gravitational waves by means of int erferometric antennas DTSTART;VALUE=DATE-TIME:20171002T121000Z DTEND;VALUE=DATE-TIME:20171002T150000Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-12@cern.ch DESCRIPTION:Speakers: Liudmila Fesik (PhD student)\nThere is presented a n ew method for the determination of a polarization state of an incoming gra vitational wave (GW) by means of a network of three and more working inter ferometric antennas when the source localisation is known. The recent anno uncement 1st August 2017 about the start of the new observation run with t hree interferometric antennas of LIGO-Virgo Collaboration opens a new poss ibility for the study of the fundamental physics of the gravitational inte raction. Modern gravitational theories predict the existence of several po larization states of gravitational waves including scalar and tensor modes \, which can be recognised by this method using the difference in beam pat terns of interferometric antennas. Therefore\, this method distinguishing between polarization modes provides a new test on a theory of gravitation. \n\nhttps://indico.particle.mephi.ru/event/14/contributions/12/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovsky hall URL:https://indico.particle.mephi.ru/event/14/contributions/12/ END:VEVENT BEGIN:VEVENT SUMMARY:Results of the space mission RadioAstron DTSTART;VALUE=DATE-TIME:20171003T073000Z DTEND;VALUE=DATE-TIME:20171003T080000Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-11@cern.ch DESCRIPTION:Speakers: Yuri Kovalev (Lebedev Physical Institute)\nThe Radio Astron Space VLBI mission utilizes the 10-m radio telescope on board the d edicated Spektr-R spacecraft to observe cosmic radio sources with an unpre cedented angular resolution at 92\, 18\, 6 and 1.3 cm. The longest baselin e of the space-ground interferometer is about 350 000 km. It successfully operates since 2011 together with up to 40 largest ground radio telescopes . Formal resolution as high as 8 and 11 microarcsec has been achieved for mega-masers and quasars observed at 22 GHz\, respectively. Successful resu lts have been obtained in all areas of its science program including activ e galactic nuclei\, pulsars and scattering\, galactic and extragalactic ma sers. In particular\, the survey of active galactic nuclei has found that cores of quasars are at least one order of magnitude brighter than what wa s known previously. This has critical physical implications for physics of jet emission in active galaxies. A new scattering effect was discovered f rom observations of both pulsars and quasars. It allows scientists to esti mate parameters of scattering screens as well as provides a new window of opportunity to reconstruct true images of background sources distorted by scattering. We will review the current status of the RadioAstron Space ver y long baseline interferometer and its main science results.\n\nhttps://in dico.particle.mephi.ru/event/14/contributions/11/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovsky hall URL:https://indico.particle.mephi.ru/event/14/contributions/11/ END:VEVENT BEGIN:VEVENT SUMMARY:The reactor antineutrino anomaly and low energy threshold neutrino experiments DTSTART;VALUE=DATE-TIME:20171004T063000Z DTEND;VALUE=DATE-TIME:20171004T064500Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-10@cern.ch DESCRIPTION:Speakers: Estela A. Garces (CINVESTAV)\nShort distance reactor antineutrino experiments measure an antineutrino spectrum a few percent l ower than expected from theoretical predictions. In this work we study the potential of low energy threshold reactor experiments in the context of a light sterile neutrino signal. We discuss the perspectives of the recentl y detected coherent elastic neutrino-nucleus scattering in future reactor antineutrino experiments. We find that the expectations to improve the cur rent constraints on the mixing with sterile neutrinos are promising. We al so analyse the measurements of antineutrino scattering off electrons from short distance reactor experiments. In this case\, despite the statistics is not competitive with inverse beta decay experiments\, the restrictions play an important role when we compare it with the Gallium anomaly.\n\nhtt ps://indico.particle.mephi.ru/event/14/contributions/10/ LOCATION:Hotel Intourist Kolomenskoye 4* Petrovsky hall URL:https://indico.particle.mephi.ru/event/14/contributions/10/ END:VEVENT BEGIN:VEVENT SUMMARY:Nonlinear electrodynamics\, regular black holes and wormholes DTSTART;VALUE=DATE-TIME:20171002T121000Z DTEND;VALUE=DATE-TIME:20171002T150000Z DTSTAMP;VALUE=DATE-TIME:20260811T202045Z UID:indico-contribution-14-9@cern.ch DESCRIPTION:Speakers: Kirill Bronnikov (VNIIMS)\nA brief review of the exi sting regular models in general relativity coupled to nonlinear eelctrodyn amics (NED). These include regular\, purely magnetic black holes and solit on-like configurations with a regular center and dynamic wormholes with a magnetic source.
