2023-02-17 ANisotropic Flow in high baryon density region doi:10.57760/sciencedb.j00186.00049 en We report a systematic study of the first two Fourier coefficients v1 and v2 in the center of mass energy range 2.11-4.9 GeV within the framework of a hadronic transport model (UrQMD). Recent results from the STAR experiment were used to test the model calculations. A mean-field mode with strong repulsive interaction is needed to reproduce the 10-40% centrality data at 3 GeV. This implies that hadronic interactions play an important role in the collective flow development in the high baryon density region. The mean values of the freeze-out time for protons and pions are shifted earlier owing to the additional repulsive interactions. We predict the energy dependence of the mean values of transverse momentum, v1, and v2 for both protons and pions from the Au+Au collisions.
