11th International Conference on Hard and Electromagnetic Probes of High-Energy Nuclear Collisions

The second-order Fourier coefficients ($v_{2}$) of $\Upsilon$(1S) and J/$\psi$ 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 $\Upsilon$(1S) $v_{2}$ 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.
