Brief annotation and scientific rationale:

Expected results upon completion of the project:

Obtaining information about the properties of excited nuclear matter. Participation in experiments with nuclei and polarized protons at the STAR facility at the RHIC nuclear collider at BNL.
Measurement at the STAR facility of spin effects in experiments with polarized protons. Obtaining new information about the spin – dependent distribution functions of quarks and gluons in the proton.
Research of femtoscopic correlations, structure of events and scaling properties of nuclear interactions, global polarization, events with wide transverse momenta.
Conducting experiments on the Beam Energy Scan program BESII in the collider mode and in the fixed target mode. Search for signatures of phase transitions and critical points of QCD.
Development of the STAR detector software and creation of corresponding infrastructure at JINR for processing and analysis of experimental data of the STAR facility at JINR.
Creation of the joint educational programs in relativistic nuclear physics and physics of the microworld together with BNL and JINR member states universities.

Expected results of the project in the current year:
