Scientific Programme:
Search for manifestation of quark-gluon degrees of freedom in collisions of relativistic nuclei and phase transitions in nuclei and exotic resonances. Study of nuclear multifragmentation processes. The Nuclotron internal target experiments. Asymptotics in nuclear collisions and nucleon clusters. Detector development for relativistic heavy-ion experiments at the CERN and BNL. Investigation of the interactions of nuclei at energy 20-158 GeV on a nucleon on NA61/SHINE experiment (SPS, CERN). Study of hadron production in hadron-nucleus interactions. Use of these data for precise predictions of neutrino fluxes in neutrino oscillation experiments at accelerators. Study of fragmentation of light stable and radioactive nuclei with beams of secondary nuclei and data analysis. Studies of cluster structure of light stable and radioactive nuclei in relativistic dissociation. Studies of multifragmentation of heavy nuclei. Study of the properties strong interaction matter. Study of the particles properties in nuclear matter at the Nuclotron.

Expected main results in 2017:
  • Continuation of experiments with the internal target at the Nuclotron. Preparation and carrying out of experiments with extracted beams at the Nuclotron. Development of the software for modeling and processing experimental data.

  • Participation in realization NA61. Study of hadron production in proton-carbon interactions at 30 GeV in the NA61/SHINE experiment at CERN. Use of these data for improved predictions of neutrino fluxes and precise determination of neutrino oscillation parameters in the T2K experiment in Japan.

  • Experimental study of the properties of hot nuclei produced in the collisions of the light relativistic projectiles with heavy target. Measuring and analysis of the longitudinal versus transversal velocity componrnts of fragments in order to understand the degree of the equilibration involved in the disassembly process. The elaboration of the trigger system for decay registration of hypernuclei.

  • Study of multiparticle dynamics in terms of masses and energies of colliding objects and centrality of interaction. Mathematical modeling of experiments on investigation of the properties of highly excited states of nuclear matter in relativistic nuclear collisions and the mechanism of quark hadronization in the process of pion pair production.

  • Search for eta-mesic nuclei formed in dA collisions, the determination of the total cross section of eta-nucleus production in dA collisions and its energy and A-depedence, the construction and production of the neutron detector for this experiment. Investigation of scintillators at high beam intensity.

  • Preparation of the physical programme for experiments at SIS18 and SIS100.

  • Analysis of nuclear track emulsion exposed to the isotopes B-10 and C-11. Exposure of emulsion in secondary beam of the radioactive isotope Be-10. Exposures to heavy nuclei. Test exposures of emulsion in range of hundreds MeV per nucleon.

  • Study of nuclear interactions depending on projectile mass and energy with the beams of relativistic nuclei at the Nuclotron and other accelerators with the photo-emulsion method. Study of fragmentation, multifragmentation, multiparticle production together with correlations between them at interaction of nuclei of various energies with photo-emulsion nuclei. Search for collective effects in central nuclear-nuclear collisions in photo-emulsions.

  • Search and study of new phenomena based on the data obtained using bubble chambers; Theoretical interpretation of these results. Creation of the data base of experimental data and educational programs in the field of relativistic nuclear physics.

  • Study of deep subthreshold processe, applied and educational programs at MARUSYA setup. Construction of electromagnetic detector of MARUSYA setup and test channel and corresponding electornics for detector testing.

  • Investigations with light and heavy ions for applied research.

  • Elaborate schemes of measurement and experimental study (energy and time resolutin) of the hadron calorimeter, designed to monitor and mesure the luminosity at the collider NICA, and the neutron detector, designed for the study of nuclear structure isospin internucleonic on small distances. It uses beam-formed channel 4B and installing infrastructure of the SPHERE setup.
