Issues addressed and main goals of research:
The study of new phenomena in multiple particles productions associated with the manifestation of the quark and gluon degrees of freedom in the interaction of relativistic nuclei. The study of nucleon and nuclear interactions in the VBLHEP accelerator complex, CERN SPS. Energy scan of interactions of nuclei at energies 20-158 GeV/nucleon and to study their dependence on the atomic number of nuclei. The searching of the critical point on the phase diagram of nuclear matter on the NA61(SPS, CERN) and PHENIX(BNL). Study of hadron production in hadron-nucleus interactions. The use of obtained data for precision calculations of spectra and fluxes in accelerator neutrino experiments to study neutrino oscillations. The study of claster structures in light stable and radioactive nuclei in the relativistic dissociation. A study of the multiple fragmentation of heavy nuclei. Experimental and theoretical study of deep subthreshold, cumulative processes, the formation of hadrons and antimatter in the transition energy region. A study of the behaviour of elementary particles, nucleon resonances and nucleon fluctuations in nuclear matter on the spectrometer SCAN. Preparation of proposaps of experiments at the accelerator complex of VBLHEP on the extracted beams of the Nuclotron and NICA Collider. Study of the short range nucleon-nucleo correlations and cluster structure of the nuclei using the beams of ions, polarized protons and deuterons at the internal target of Nuclotron in the framework of DSS and SCAN-3 projects.
