The second-order Fourier coefficients ( ) characterizing the azimuthal distributions of Υ(1S) and Υ(2S) mesons produced in PbPb collisions at are studied. The Υ mesons are reconstructed in their dimuon decay channel, as measured by the CMS detector. The collected data set corresponds to an integrated luminosity of . The scalar product method is used to extract the coefficients of the azimuthal distributions. Results are reported for the rapidity range , in the transverse momentum interval , and in three centrality ranges of 10–30%, 30–50% and 50–90%. In contrast to the mesons, the measured values for the Image 5 mesons are found to be consistent with zero.
