The [Formula presented] 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 [Formula presented] mesons are found to be consistent with zero.engopenAccesshttps://creativecommons.org/licenses/by/4.0/article81900067925920004610.1016/j.physletb.2021.1363855.02 TeVCMSFlowHeavy ionPbPbUpsilon2-s2.0-85111180510
