Description
We study the elliptic flow (${v_2}$) in the framework of PACIAE2.1b model. The theoretical results of charged hadrons (K, p, $\pi $ ) as a function of transverse momentum (${p_T}$) dependence and pseudorapidity ($\eta$) dependence are compared with LHC and RHIC experimental data in Pb+Pb and Au+Au collisions at center of mass energy 0.2 - 2.76 TeV. The results cover a broad kinematic range, $ 0.3 < {p_T} < 20 $ , $ \left| \eta \right| < 2.4 $.
It is found that a moderate increase in ${v_2}\left( {{p_T}} \right)$ at low ${{p_T}}$ from the highest RHIC to LHC, destpite the large increase in the center of mass systematic uncertainties.The value of ${v_2}\left( \eta \right)$ is found to be weakly dependent on pseudorapidity in central collisions for peripheral collisions the values of ${v_2}\left( \eta \right)$ gradually decrease as the pseudorapidity increase.
