摘要：
In this article, we report on the measurements of J/psi invariant yields as a function of transverse momentum at midrapidity (vertical bar y vertical bar<1.0) in Au+Au collisions at root s(NN) = 39, 62.4 and 200 GeV taken in 2010 by STAR with full Time-of-Flight detector and Barrel Electromagnetic Calorimeter detector in operation. Centrality dependence of J/psi production and nuclear modification factors are presented. Comparisons among different collision energies and model calculations are discussed.
