Anisotropic flow in high baryon density region
文献摘要：
Collective flow is a powerful tool used to ana-lyze the properties of a medium created during high-energy nuclear collisions.Here,we report a systematic study of the first two Fourier coefficients v1 and v2 of the proton and π+from Au+Au collisions in the energy range √SNN=2.11-4.9 GeV within the framework of a hadronic transport model(UrQMD).Recent results from the STAR experi-ment were used to test the model calculations.A mean-field mode with strong repulsive interaction is needed to reproduce the 10-40％data at 3 GeV.This implies that hadronic interactions play an important role in the collec-tive flow development in the high baryon density region.The mean values of the freeze-out time for protons and π+are shifted earlier owing to the additional repulsive inter-actions.We predict the energy dependence of the mean values of the transverse momentum,vi,and v2 for both protons and π+from the Au+Au collisions.
