Description
Charmonia, such as the J/$\psi$ and $\psi$(2S) mesons, are important probes of the quark-gluon plasma (QGP). The measurement of their nuclear modification factor, elliptic and triangular flow can provide strong constraints for the mechanism of in-medium energy loss. In this talk, results on the relative J/$\psi$ and $\psi$(2S) modification, based on the pp and PbPb data collected at $\sqrt{s)_{NN}}$ = 5.02 TeV by CMS, will be reported. Also we present the second-order and third-order Fourier coefficients, $v_{2}$ and $v_{3}$ for prompt and nonprompt J/$\psi$ and prompt $\psi$(2S) mesons. In addition, the nuclear modification factor of charmonia in PbPb collisions will be reported.
