description: The most important sign of the formation of QGP in the process of matter evolution in relativistic ion collisions at high energies is the presence of azimuthal anisotropy of the distribution of the particles being generated. Therefore, special attention is paid to the study of the formation of elliptic flows based on experimental data, as well as theoretical calculations and multicomponent modeling. In this paper, we study the theoretical foundations of the AMPT model, which includes several phases of the evolution of hadron and partonic matter, as well as the influence of some mechanisms of particle interaction during the evolution of hadron matter on the formation of elliptical flows of Ï^0-mesons. Based on this information, the elliptic flows v_2 of Ï^0-mesons in Cu+Au collisions at the energy â(s_NN )=200 GeV in different centers were calculated. The dependences of v_2 on the transverse momentum p_T were constructed for different values of the parton-parton cross section in the parton cascade stage, which were compared with the experimental data obtained in the PHENIX experiment.
