Abstract
The second-order Fourier coefficients (v2) characterizing the azimuthal distributions of Υ(1S) and Υ(2S)
mesons produced in PbPb collisions at √sNN = 5.02 TeV 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 1.7 nb−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 < 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 v2 values for the Υ mesons are found to be consistent with
zero.
