Abstract
We report the first measurement of the azimuthal anisotropy of J/ψ at forward rapidity [Formula Presented] in Au + Au collisions at [Formula Presented] GeV at the BNL Relativistic Heavy Ion Collider. The data were collected by the PHENIX experiment in 2014 and 2016 with integrated luminosity of 14.5 nb−1. The second Fourier coefficient (ν2) of the azimuthal distribution of J/ÿ is determined as a function of the transverse momentum [Formula Presented] using the event-plane method. The measurements were performed for several selections of collision centrality: 0%–50%, 10%–60%, and 10%–40%. We find that in all cases the values of ν2(pT), which quantify the elliptic flow of J/ÿ, are consistent with zero. Within uncertainties, the results are consistent with measurements at midrapidity, indicating no significant elliptic flow of the J/ÿ within the quark-gluon-plasma medium at collision energies of [Formula Presented] GeV.
