Description
We report the measurements of μ+μ− pair production for pT< 0.10 GeV/c in 40-80% Au+Au collisions at √SNN = 200 GeV at STAR. A significant enhancement with respect to the hadronic cocktail is observed. The pT2 and ∆ϕ distributions of the excess yields are also reported and compared with model calculations. The EPA-QED calculations can describe the data very well within uncertainties.
