Di-lepton production in p+p collisions at $\sqrt{s_{_{NN}}} = 200$ GeV from STAR

Abstract

The di-electron analysis for 200 GeV p+p collisions is presented in this article. The cocktail simulations of di-eletrons from light flavor meson decays and heavy flavor decays are reported and compared with data. The perspectives for di-lepton measurements in Au+Au collisions are discussed.
