Nuclear Deformation Effect on Azimuthal Anisotropy Simulation in the HYDJET++ Monte Carlo Generator

Results of a study of the azimuthal anisotropy in Pb–Pb and Xe–Xe collisions at LHC energies in the HYDJET++ generator are presented. The dependences of the differential coefficients of the azimuthal flow vₙ and the dependences of the integral coefficients of the flow were analyzed. A comparison was made with experimental data from the CMS collaboration. Although HYDJET++ reproduces the main trends for azimuthal flows, a number of discrepancies indicate the importance of consideration of the initial system geometry. The results obtained serve as guidelines for further improvement of hydrodynamic models.
