Beschreibung

The second- and third-order Fourier coefficients of charmonium states are measured in PbPb collisions with CMS. With this new analysis, extending to a higher $p_\mathrm{T}$ region, we investigate further the high-$p_\mathrm{T}$ J/$\psi$ $v_{2}$ in heavy ion collisions. The nonprompt J/$\psi$ $v_{2}$ probes the different behavior of charm and bottom quarks induced by interactions with the QGP medium. The $v_{3}$ flow coefficient values, for the separated prompt and nonprompt J/$\psi$ as well as the prompt $\psi$(2S), are reported for the first time.
