Investigation of in-medium effects of charmonia using azimuthal anisotropy and jet fragmentation function in PbPb collisions at √S NN = 5.02 TeV with the CMS experiment

Quarkonia have been long proposed as the golden probes to study quark-gluon plasma (QGP) in heavy-ion collisions. In this presentation, we present the second- and third-order Fourier coefficients, v 2 and v 3 , for prompt and nonprompt J/ψ mesons in PbPb collisions as functions transverse momentum ( p T) and PbPb collision centrality. Also, we report the first measurements of v 2 and v 3 for the prompt ψ(2S) mesons in PbPb collisions. The results provide v 2 and v 3 values over the wide studied kinematics regions of transverse momentum and collision centrality.
