Abstract (data abstract)
CERN-LHC. The second-order ($v_{2}$) and third-order ($v_{3}$) Fourier coefficients describing the azimuthal anisotropy of prompt and nonprompt J/$\psi$ and prompt $\psi$(2S) mesons are measured in lead-lead (PbPb) collisions at the center-mass-energy per nucleon at 5.02 TeV. The analysis uses a data set corresponding to an integrated luminosity of 1.6 inverse nanobarns recorded with the CMS detector in 2018. The J/$\psi$ and $\psi$(2S) mesons are reconstructed using their dimuon decay channel. The $v_{2}$ and $v_{3}$ coefficients are extracted using the scalar product method and studied as functions of meson transverse momentum and PbPb collision centrality. The measured $v_{2}$ values for the prompt J/$\psi$ mesons are found to be larger than those for nonprompt J/$\psi$ mesons. The separated prompt and nonprompt J/$\psi$ mesons $v_{3}$ and prompt $\psi$(2S) meson $v_{n}$ values are reported for the first time, providing new insights into the understanding of quarkonium dynamics in heavy ion collisions.
