$J/\psi$ production in PHENIX

Nuclear Experiment 2019-08-14 v1

Abstract

Heavy quarkonia production is expected to be sensitive to the formation of a quark gluon plasma (QGP). The PHENIX experiment has measured J/ψJ/\psi production at sNN=\sqrt{s_{NN}}=~200 GeV in Au+Au and Cu+Cu collisions, as well as in reference p+p and d+Au runs. J/ψJ/\psi's were measured both at mid (y<0.35|y|<0.35) and forward (1.2<y<2.21.2<|y|<2.2) rapidity. In this letter, we present the A+A preliminary results and compare them to normal cold nuclear matter expectations derived from PHENIX d+Au and p+p measurements as well as to theoretical models including various effects (color screening, recombination, sequential melting...).
