Аннотация:The article presents the results of modeling the heavy-ion collisions of xenon and lead systems in the Monte Carlo generator HYDJET++. The relations of the azimuthal distributions of charged particles in Xe–Xe and Pb–Pb collisions are given. The simulation results are compared with the CMS experiment. In addition, predictions are given for the azimuthal distributions of charged particles in relativistic collisions of oxygen nuclei.
