Measurement of elliptic flow of J/ψ in √sNN=200GeV Au+Au collisions at forward rapidity

Popis výsledku v původním jazyce

We report the first measurement of the azimuthal anisotropy of J/ψ at forward rapidity (1.2<|η|<2.2) in Au+Au collisions at √sNN=200 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 (v2) of the azimuthal distribution of J/ψ is determined as a function of the transverse momentum (pT) 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 v2(pT), which quantify the elliptic flow of J/ψ, are consistent with zero. Within uncertainties, the results are consistent with measurements at midrapidity, indicating no significant elliptic flow of the J/ψ within the quark-gluon-plasma medium at collision energies of √sNN=200 GeV.
