Beschreibung

The second-order Fourier coefficients (v2) of Υ(1S) and J/ψ mesons in high-multiplicity pPb collisions is studied using data collected by the CMS experiment at a nucleon-nucleon center-of-mass energy 8.16 TeV. The dimuons used to reconstruct the heavy quarkonium states are correlated with charged hadrons using long-range two-particle correlation techniques. The measurement of the Υ(1S) v2 is reported for the first time in small collision systems. The results are discussed in the context of collectivity and modification of heavy quark dynamics.
