Abstract
In this proceeding, we presented the nuclear modification factor (RAA) of J/ψ as a function of centrality and transverse momentum in Au+Au collisions at √sNN = 14.6, 17.3, 19.6, and 27 GeV collected by STAR. The energy dependence of J/ψ RAA from RHIC to LHC energies is also investigated, and compared with model calculations. Additionally, the first measurement of ψ(2S) production in isobaric collisions at top RHIC energy is presented, including the centrality and transverse momentum dependence of the ψ(2S) over J/ψ yield ratio.
