The elliptic flow of di-electrons in $\sqrt{s_{NN}}$=200 GeV Au+Au collisions at STAR

Abstract

In minimum bias (0-80%) Au+Au collisions at $\sqrt{s_{NN}}$=200 GeV, the elliptic flow ($v_{2}$) measurements for di-electrons from the low to intermediate mass region are presented. The differential elliptic flow as a function of transverse momentum in different mass regions are also reported. The simulated and measured $v_{2}$ of di-electrons are compared in the mass regions of $M_{ee}<0.14$ GeV/$c^{2}$ and $0.14<M_{ee}<0.3$ GeV/$c^{2}$.
