Charmonia in pp, pPb and PbPb with CMS

The mechanisms through which charmonia production is modified in the high-density medium created in ultra-relativistic heavy-ion collisions are still not quantitatively understood. In order to disentangle different scenarios, a multi-dimensional analysis in a wide kinematic range is needed, in pp and AA collisions, looking at many observables that have different sensitivities to the various aspects of charmonia production. We will report on the prompt $J/\psi$ measurements with the CMS detector, using the 150 $\mu$b$^{-1}$ of PbPb data recorded in 2011. The azimuthal anisotropy in PbPb collisions at 2.76 TeV will be presented. In addition, the comparison of the excited charmonium state ($\psi(2S)$) and the ground state ($J/\psi$) between PbPb and pp is updated, utilizing the pp sample from 2013, which has a factor of 20 higher statistical precision than the 2011 pp data previously presented.
