Abstract

We study the side-ward and elliptic differential flow of protons and charged pions for Pb+Pb collisions at $40 A$ GeV and $158 A$ GeV energies in a microscopic relativistic transport simulation model. The calculation of flow results are compared with the recent data from the NA49 Collaboration as a function of transverse momenta, rapidity, and centrality. It is found that in the simulation model without potential explains the side-ward flow qualitatively well and with potential favors the elliptic flow reasonably good with the experimental data.
