Description
Summary:The second-order Fourier coefficients (v2) characterizing the azimuthal distributions of Image 3 and Image 4 mesons produced in PbPb collisions at sNN=5.02TeV 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 1.7nb−1. The scalar product method is used to extract the v2 coefficients of the azimuthal distributions. Results are reported for the rapidity range |y|<2.4, in the transverse momentum interval 0<pT<50GeV/c, and in three centrality ranges of 10–30%, 30–50% and 50–90%. In contrast to the J/ψ mesons, the measured v2 values for the Image 5 mesons are found to be consistent with zero.
