Abstract
The project focuses on the study of relativistic heavy-ion collisions at the energies of the NICA collider using micro- and macroscopic models (UrQMD, QGSM, DCM-QGSM, 3FD, and SM). The following relevant signals are studied: relaxation of hot and dense nuclear matter to the state of chemical and thermal equilibrium, equation of state of hot and dense nuclear matter, evolution of shear viscosity and its ratio to entropy density \(\eta {\text{/}}s\), emergence and development of anisotropic flow (directed, elliptic and triangular) of baryons and mesons, yields of strange mesons and hyperons, as well as vorticity and its connection with the directed flow of hadrons and polarization of (anti)hyperons. To solve these problems, it is proposed to simultaneously scan (1) the collision energy, from \(\sqrt s = 3.5\) to 11.5 GeV; (2) the collision centrality, from central 0–5% to peripheral 40–80% collisions; (3) the species of the colliding nuclei, from the light deuterium nuclei to the heavy Au + Au systems. Results of our studies for the first 1.5 yr are presented.
