英文摘要	The inclusive J/Psi transverse momentum spectra and nuclear modification factors are reported at midrapidity (\|y\| < 1.0) in Au + Au collisions at root S-NN = 39, 62.4 and 200 GeV taken by the STAR experiment. A suppression of J/Psi production, with respect to the production in p + p scaled by the number of binary nucleon-nucleon collisions, is observed in central Au + Au collisions at these three energies. No significant energy dependence of nuclear modification factors is found within uncertainties. The measured nuclear modification factors can be described by model calculations that take into account both suppression of direct J/Psi production due to the color screening effect and J/Psi regeneration from recombination of uncorrelated charm-anticharm quark pairs.
