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

Abstract

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