Abstract
The second-order Fourier coefficients (v2) characterizing the azimuthal distributions of [Formula presented] and [Formula presented] mesons produced in PbPb collisions at sjavax.xml.bind.JAXBElement@49bfafb5=5.02TeV are studied. 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 0File | Dimensione del file | Formato | |
