Investigation of in-medium effects of charmonia using azimuthal anisotropy and jet fragmentation function in PbPb collisions at √SNN = 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, v2 and v3, for prompt and nonprompt J/ψ mesons in PbPb collisions as functions transverse momentum (pT) and PbPb collision centrality. Also, we report the first measurements of v2 and v3 for the prompt ψ(2S) mesons in PbPb collisions. The results provide v2 and v3 values over the wide studied kinematics regions of transverse momentum and collision centrality. [ABSTRACT FROM AUTHOR]
