Abstract: The second-order Fourier coefficients (v2) characterizing the azimuthal distributions of ?(1S)and ?(2S)mesons produced in PbPb collisions at ?sNN=5.02TeVare studied. The ?mesons are reconstructed in their dimuondecay 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 v2coefficients of the azimuthal distributions. Results are reported for the rapidity range |y| <2.4, in the transverse momentum interval 0
