Description
Charmonia in nucleus-nucleus (A-A) collisions are an important probe to study for understanding the deconfinement in heavy ion collisions at LHC energies. The measurement in proton-lead (p-A) collisions of prompt and non-prompt $J/\psi$ production enables us to investigate nuclear matter effects and therefore, provides a new input to examine the hot-medium effects in A-A collisions, which are still not fully understood. Using CMS, the transverse momentum and rapidity differential cross-sections, and forward to backward ratios of prompt and non-prompt $J/\psi$ in pPb collisions at center of mass energy per nucleon pair = 5.02 TeV will be presented. The dependence of forward to backward ratios with respect to the event characteristics will also be shown.
