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

The second-order ($v_2$) and the third-order ($v_2$) Fourier coefficients which describe the azimuthal anisotropy of prompt and nonprompt $J/\psi$ and prompt $\psi$(2S) mesons are measured in PbPb collisions at 5.02 TeV. The $v_{2}$ and $v_{3}$ values are extracted using the scalar product method. The measured $v_{2}$ values for the prompt $J/\psi$ mesons are larger than those for nonprompt $J/\psi$ mesons. No significant nonzero $v_{3}$ values for both prompt and nonprompt $J/\psi$ mesons, reported for the first time in heavy ion collisions, are found. The prompt $\psi$(2S) meson $v_{n}$ values are reported for the first time.
