Аннотация
The PHENIX experiment at the BNL Relativistic Heavy Ion Collider (RHIC)has measured $J/\ensuremath{\psi}$ production for rapidities $\ensuremath{-}2.2<y<2.2$ in $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{{s}_{NN}}=200\text{ }\text{ }\mathrm{GeV}$. The $J/\ensuremath{\psi}$ invariant yield and nuclear modification factor ${R}_{AA}$ as a function of centrality,transverse momentum, and rapidity are reported. A suppression of $J/\ensuremath{\psi}$ relative to binary collision scaling of proton-protonreaction yields is observed. Models which describe the lower energy $J/\ensuremath{\psi}$ data at the CERN Super Proton Synchrotron invoking only $J/\ensuremath{\psi}$ destruction based on the local medium density predicta significantly larger suppression at RHIC and more suppression at midrapiditythan at forward rapidity. Both trends are contradicted by our data.
