Charmonium production in pPb and PbPb collisions at 5.02 TeV with CMS

Charmonium states, such as the J/$\psi$ and $\psi$(2S) mesons, are excellent probes of the deconfined state of matter, the Quark-Gluon Plasma (QGP) created in heavy ion collisions. In addition, the measurements in pPb collisions allow to study the cold nuclear matter effects, being crucial to disentangle these from the QGP-related effects in PbPb collisions. In this talk the new nuclear modification factor $R_{\mathrm{AA}}$ of prompt and nonprompt J/$\psi$ in PbPb collisions at \mbox{$\sqrt{s_{\mathrm{NN}}}$} $= 5.02$ TeV were presented over a wide kinematic (3 $< \ensuremath{p_{\mathrm T}} <$ 50 GeV/$c$, $\lvert y \rvert<$ 2.4), and fine event-centrality intervals. The results were compared to those at 2.76 TeV over a similar kinematic range. In addition, new prompt $\psi$(2S) $R_{\mathrm{AA}}$ results at 5.02 TeV were reported. Finally the final prompt and nonprompt J/$\psi$ results, as well as preliminary $\psi$(2S) results, in pPb collisions at 5.02 TeV, were briefly discussed.
