【 摘 要 】

We report on recent STAR results on Jψψ and Υ production and suppression at midrapidity in Au+Au collisions at RHIC. We present the Jψψ nuclear modification factor as a function of centrality and transverse momentum at 200, 62.4 and 39 GeV and discuss the energy dependence of Jψψ production. We also present the Υ nuclear modification factor in Au+Au collisions at 200 GeV calculated using high statistics p+p data taken in 2009.
