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. © 2021 The Author(s)Elsevier B.V.2021Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/13357https://doi.org/10.1016/j.physletb.2021.1363850370-2693enPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physicsinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/13357
