Study of azimuthal anisotropy of Υ(1S) mesons in pPb collisions at √ NN = 8.16TeV

The azimuthal anisotropy of Υ(1S) mesons in high-multiplicity proton-lead collisions is studied using data collected by the CMS experiment at a nucleon-nucleon center-of-mass energy of 8.16TeV. The Υ(1S) mesons are reconstructed using their dimuon decay channel. The anisotropy is characterized by th...
