| dc.description | $J/ψ$ production has been measured in Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}}$ = 200 GeV by the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) during 2004 and 2005, respectively, at mid-rapidity ($|η| \le$ 0.35) via $J/ψ$ $\to$ $e^{+}e^{-}$ decay and at forward rapidity (1.2 $\le | η| \le$ 2.2) via $J/ψ$ $\to$ $μ^{+}μ^{-}$ decay. The nuclear modification factor ($R_{AA}$) of $J/ψ$ is presented as a function of the collision centrality for Au+Au collisions (final results) and Cu+Cu collisions (preliminary results) in both rapidity windows. These results are compared to SPS results at lower energy and to various theoretical calculations. | |
