Issues addressed and main goals of research:
Development of the infrastructure for spin physics research at the Nuclotron-M/NICA and other facilities. Preparation of the spin control and polarimetry system projects. Measurement of analyzing power in the reaction of polarized protons and polarized neutrons with polyethylene target at the momentum up to 7.5 GeV/c and up to 6.0 GeV/c for polarized proton and neutron respectively at the setup ALPOM-2. Study of 2N- and 3N-correlations in deuteron-proton elastic scattering and deuteron break-up reactions at the Nuclotron internal target. Measurement of the cross sections and deuteron analyzing powers of the reactions. Completion of the data analysis obtained at the setup Delta-Sigma. Preparation of the proposals on modernization of the spectrometer and the Saclay-Argonne-JINR polarized proton target (setup PPT). Obtained new data on the studying of charge-exchange processes in the interactions of polarized deuterons and protons 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. Works on the program of the setup DELTA-2 design INR RAN/JINR.
Expected results in the current year:
- Works:
a) complation of preparation of the project of low energy proton and deuteron polarimeter at the Nuclotron injection channel;
b) work on the project of high energy proton and deuteron polarimeter for the NICA complex.
- Fulfilment of the works in accordance with the approved projects and collaborative protocols within the frames of their real financial support, including realization of the projects ALPOM-2 abd DSS. Development and manufacture of the proton polarimeter at the Nuclotron internal target. Analysis of the data on the analyzing powers Ay, Ayy and Axx in deuteron-proton elastic scattering at the energies 400-1300 MeV. Publication and reports of the results.
- Participation in the development of the BM@N setup elements in accordance with general plan.
- Participation in the joint scientific programs and experiments, design and test of
the new detectors elements at the other facilities SPS, LHC, FCC (CERN), RHIC (BNL), MEIC (TJNAF), FAIR (GSI).
- Continuation of the development of the new methods to calculation of the amplitudes and polarization characteristics of deuteron fragmentation and
deuteron elastic scattering on protons and nuclei taking into account FSI and relativistic effects.
