Measurements of the directed and elliptic flow of strange and multi-strange hadrons are an important part of the physics program of the Compressed Baryonic Matter experiment (CBM) at the future accelerator complex FAIR in Darmstadt, Germany. It was shown recently by studies from RHIC BES program that $dv_{1}/dy \vert_{y=0}$ and the difference between $v_{2}$ of particles and antiparticles in...

Models of 3-d dot potential - model with a derivative and integrated model are studied. Unlike usually used model with a derivative,
the integrated model allows smooth transition of a condition of two centers in a condition of one center at reduction of distance between centers
to zero. The model of pointed interactions adequately describes real nuclear interactions. The studied...

After the Higgs boson discovery at the LHC, a lot of additional measurements should be performed to make sure that the observed particle is the Standard Model Higgs boson. These measurements include cross sections measurements, couplings measurements, studies of the interaction vertex structures etc. One of the most perspective things to study is the kinematics of the production jets,...

Experimental data on inelastic $^{9}Be$+$\alpha$ scattering induced by 90 and 30 MeV α particles are analyzed. The question of the formation of a third rotational band based on the 2.78 MeV state is considered. The assumption is made about the occurrence of the 3.82 MeV state in the third rotational band.

We present a review of results in SUSY searches in VBF topology with 8 TeV data collected by the CMS experiment. A 13 TeV projection of this searches is presented with a report on the mu+VBF trigger performance using 2017 data collected.

Measurements 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 excitation function of the virtual photon radiation from dense nuclear matter. A large excess of the dilepton yield in the intermediate (0.14 < M < 0.6 GeV/c2) mass region points to a strong source generated from the high-density zone of...

A modular hadron calorimeter, the Projectile Spectator Detector (PSD) at
CBM is aimed to determine a collision centrality and to reconstruct the
event plane orientation in collisions of heavy nuclei. PSD is a hadron
lead/scintillator sandwich calorimeter with the sampling ratio providing
the compensation condition. The calorimeter includes 44 individual
modules. Each module consists of 60...

Forward hadron calorimeter (FHCAL) is intended for the measurements of the geometry of heavy ions collisions. The main purpose of the FHCAL is to provide an experimental measurement of a heavy-ion collision centrality and orientation of its reaction plane. FHCAL consists of two identical arms placed at the left/right sides from the beam collision point. This is a modular lead-scintillator...

When seen in gamma rays, the Moon appears brighter than the Sun. Gamma rays emitted by the Moon mostly originate from the decays of neutral pions produced by the interactions of cosmic rays with the lunar surface. Using the data collected by the Fermi LAT in its first seven years of operation, we measured the gamma-ray emission spectrum of the Moon in the energy range from 30 MeV up to a few...

If quantum vacuum fluctuations are virtual gravitational dipoles, the gravitational charge density of the quantum vacuum is obviously equal to zero. While very counterintuitive this is the most elegant and the simplest solution to the cosmological constant problem. It is intriguing that in spite of the fact that the total gravitational charge of the quantum vacuum is zero, the gravitational...

We study formation and evolution of solitons within a model with two real scalar fields with the potential having a saddle point. The set of these configurations can be split into disjoint equivalence classes. We give a simple expression for the winding number of an arbitrary closed loop in the field space and discuss the evolution scenarios that change the winding number. These non-trivial...

Separation of electroweak from strong $Z\gamma$ production is a very challenging task due to identical final states of such processes. The only difference is the origin of two leading jets. Rectangular cuts on jet kinematical variables from ATLAS Run1 $Z\gamma$ analysis were improved using machine learning techniques. New selection variables were also tested. The reached expected significance...

*The Russian long-term **'PHOENIX'** Space Experiment* started in November 2014 with the purpose of investigating the impact of space radiation on genetic properties and survival of biological samples exposed on-board the **International Space Station**. Such projects require detailed knowledge on the composition, fluxes and doses of various components of cosmic radiation. To solve this...

One important result from recent large integral field spectrograph (IFS) surveys is that the intrinsic velocity dispersion of galaxies increases with redshift. Massive, rotation-dominated discs are already in place at z~2, but they are dynamically hotter than spiral galaxies in the local Universe. Although several plausible mechanisms for this elevated velocity dispersion (e.g. star formation...
