Scientific Programme:
Methodical support of the experiments at polarized beams of the Nuclotron-M and NICA facilities, including development of polarimetery systems. Measurement of analyzing power for the reaction p + CH2 at polarized proton momentum up to 7.5 GeV/c at the setup ALPOM-2. Measurement of tensor analyzing power and spin correlation in d p reaction in the deuteron core area with the use of polarized 3He target and polarized deuteron beam of the Nuclotron-M. Study of 2N- and 3N-correlations in deuteron-proton elastic scattering and deuteron break-up reactions at the Nuclotron internal target. Works on modernization of Saclay-Argonne-JINR polarized proton target (setup PPT). The analysis of set of the np spin observables at 0 o (the total np cross section differences), using polarized targets and quasi-monochromatic relativistic 1.2-3.6 GeV neutron beams. Determination of the forward scattering NN amplitudes over this energy region. Comparison of the obtained data with QCD motivated model calculations. Study of charge-exchange processes in dp--interactions at the setup STRELA. Development of theoretical models for description of the simplest nuclear systems taking into account relativistic effects, meson and quark-gluon components of the internal movement. Theoretical analysis of experimental data obtained at Nuclotron-M. The study of the properties of strongly interacting matter utilizing polarization phenomena in hadron-nucleon and lepton-nucleon interactions, and in the decay of polarized radioactive atomic nuclei. Study of highly excited nuclear matter and collective effects in nuclear media; delta and other nucleonic resonance excitations on protons and nuclei. Preparation of the setup DELTA-LNS and data taking on the light neutral mesons production in polarized nucleons and nucleus interactions.
