Özet
The second-order (v (2)) and third-order (v (3)) Fourier coefficients describing the azimuthal anisotropy of prompt and nonprompt (from b-hadron decays) J/psi, as well as prompt psi (2S) mesons are measured in lead-lead collisions at a center-of-mass energy per nucleon pair of root s (NN)= 5.02 TeV. The analysis uses a data set corresponding to an integrated luminosity of 1.61 nb (-1) recorded with the CMS detector. 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 collision centrality. The measured v (2) values for prompt J/psi mesons are found to be larger than those for nonprompt J/psi mesons. The prompt J/psi v (2) values at high pT are found to be underpredicted by a model incorporating only parton energy loss effects in a quark-gluon plasma medium. Prompt and nonprompt J/psi meson v (3) and prompt psi (2S) v (2) and v (3) values are also reported for the first time, providing new information about heavy quark interactions in the hot and dense medium created in heavy ion collisions.
