Charmonium production in pp, p+Pb and Pb+Pb collisions with CMS experiment

We report the measurements of the prompt and non-prompt J/ψ and ψ(2S) nuclear modification factors (R AA) using pp and PbPb data and the RpPb using pPb data collected by CMS at the LHC. All measurements were performed via the dimuon decay channel. The R AA analysis is based on PbPb and pp data samples collected at √s NN = 5.02 TeV in 2015, corresponding to integrated luminosities of 464 μb−1 and 28 pb−1. These measurements are performed in the dimuon rapidity range of |y| < 2.4 as a function of centrality, rapidity, and transverse momentum (p T) from p T = 3GeV/c in the most forward region and up to 50 GeV/c. The R pPb analysis based on pPb data, is performed for prompt J/ψ and ψ(2S) in different kinematic bins of p T and rapidity.
