Recent J/ψ results in p+p and Au+Au collisions from STAR

In these proceedings, we present the measurements of inclusive J/ψ production at mid-rapidity region (|y| < 1.0) in Au+Au collisions at √S_NN = 54.4 GeV by the STAR experiment. The dependences of nuclear modification factor (R_AA) on centrality and transverse momentum (p_T) are presented and compared to model calculations. No significant energy dependence of R_AA is found within uncertainties. We also report the distribution of z(J/<) = p_T^J/</p_T^jet and the fraction of J/ψ produced within a charged jet at mid-pseudorapidity (|η| < 0.6) with kinematic cuts of p_T^jet > 10 GeV/c and p_T^J/< > 5 GeV/c in p+p collisions at √S = 500 GeV. Comparisons to model calculations are presented and physics implications are discussed.
