The suppression of J/ψ production in heavy-ion collisions compared to p+p collisions, caused by the color screening in the deconfined medium, has been proposed as a signature of the formation of the Quark-Gluon Plasma. However, J/ψ production rates are also sensitive to other effects such as the cold nuclear matter effects and recombination. To understand the interplay of these mechanisms, it is important to study J/ψ production for different collision geometries.
In these proceedings, we present recent result on J/ψ production via the di-electron decay channel from the STAR experiment at RHIC in p+p collisions at √sNN = 200, 500 GeV, in d+Au collisions at √sNN = 200 GeV and in heavy-ion collisions, specifically Au+Au collisions at √sNN = 200 GeV and U+U collisions at √sNN = 193 GeV. We also show measurements on J/ψ production via the di-muon decay channel in p+p collisions at √sNN = 500 GeV and in Au+Au collisions at √sNN = 200 GeV using the newly installed Muon Telescope Detector.
