Elliptic and Triangular Flow of Identified Particles from the AMPT Model at RHIC Energies

Abstract

The elliptic flow ($v_2$) at $\sqrt{s_{\mathrm{NN}}}=$ 11.5, 39, and 200 GeV and triangular flow ($v_3$) at $\sqrt{s_{\mathrm{NN}}}=$ 200 GeV of identified particles (${\pi }^{\pm },K^{\pm },K_S^0,p,\bar{p},\varphi ,\Lambda$ and $\bar{\Lambda }$) from 0\%--80\% central Au+Au collisions are analyzed using a multiphase transport (AMPT) model. It is shown that the experimental results from the $\eta$-sub event plane method can be reproduced with a parton scattering cross section between 1.5 and 3 mb. We also studied the differential and integrated $v_2/v_3$ ratios and conclude that they are anti-corrected with the parton scattering cross section.
