The inclusive production of the charmonium state ψ ( 2 S ) was studied in p-Pb and Pb-Pb collisions at s NN = 8.16 TeV and 5.02 TeV respectively, using the ALICE detector at the CERN LHC. The ψ ( 2 S ) is less bound than the J / ψ and it represents an interesting probe for the study of cold nuclear matter effects in p-Pb collisions, while in the Pb-Pb system its formation can be strongly influenced by QGP production. The measurements are performed in different center-of-mass rapidity ranges, 2.03 < y cms < 3.53 and −4.46 < y cms < −2.96 for p-Pb collisions and 2.5 < y cms < 4.0 for Pb-Pb collisions, down to zero transverse momentum, through the ψ ( 2 S ) → μ + μ - decay channel. The results are compared to those obtained for the J / ψ and with theoretical predictions.

Nuclear Modification Factors

In these proceedings, we present the latest measurements of J/ψ and ϒ by the STAR experiment. The J/ψ and ϒ production measured in p+p collisions provide new baselines for similar measurements in Au+Au collisions, while the measurements in p+Au collisions can help quantify the cold nuclear matter effects. The J/ψ υ2 is measured in both U+U and Au+Au collisions to place constraints on the amount of J/ψ arising from recombination of deconfined charm and anti-charm pairs. Furthermore, the nuclear modification factors for ground and excited ϒ states as a function of transverse momentum and centrality are presented, and compared to those measured at the LHC as well as to theoretical calculations.
