Recent measurements of quarkonium production in p+pp+p and A + A collisions from the STAR experiment

We report the measurements by the STAR Collaboration of J/ψJ/ψ invariant yields as a function of transverse momentum at mid-rapidity (|y|<1.0|y|<1.0) in p+pp+p collisions at s=500 GeV, in Au+AuAu+Au collisions at sNN=39, 62.4 and 200 GeV, and in U+UU+U collisions at sNN=193 GeV. The centrality, beam energy and collision system dependences of J/ψJ/ψ production and nuclear modification factors are discussed. We also report the ratio of ψ(2S)ψ(2S) to J/ψJ/ψ yields in p+pp+p collisions at s=500 GeV and ϒ   production in U+UU+U collisions at sNN=193 GeV.
