Özet
The second-order Fourier coefficients (v 2) characterizing the azimuthal distributions of Image 3 and Image 4 mesons produced in PbPb collisions at s NN= 5.02 TeV are studied. The Image 5 mesons are reconstructed in their dimuon decay channel, as measured by the CMS detector. The collected data set corresponds to an integrated luminosity of 1.7 nb− 1. The scalar product method is used to extract the v 2 coefficients of the azimuthal distributions. Results are reported for the rapidity range| y|< 2.4, in the transverse momentum interval 0< p T< 50 GeV/c, and in three centrality ranges of 10–30%, 30–50% and 50–90%. In contrast to the J/ψ mesons, the measured v 2 values for the Image 5 mesons are found to be consistent with zero.
