Özet
We report the first measurement of the azimuthal anisotropy of J/psi at forward rapidity (1.2 < vertical bar eta vertical bar < 2.2) in Au + Au collisions at root s(NN) = 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 (v(2)) of the azimuthal distribution of J/psi is determined as a function of the transverse momentum (p(T)) 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 v(2) (p(T)), which quantify the elliptic flow of J/psi, are consistent with zero. Within uncertainties, the results are consistent with measurements at midrapidity, indicating no significant elliptic flow of the J/psi within the quark-gluon-plasma medium at collision energies of root s(NN) = 200 GeV.
