【 摘 要 】

In minimum-bias (0-80%) Au+Au collisions at √ sNN = 200 GeV, the elliptic ow (v2) measurements of di-electrons for the low mass region (Mee2) are presented. The differential v2as a function of transverse momentum in diffrent mass regions are also reported. The simulated and measured v2of di-electrons are compared in the low mass region.
