Recent $J/\psi$ results measured with PHENIX

Abstract

Finalized PHENIX results are presented on $J/\psi$ modification from the RHIC system-size scan, which include $p$+Al, $p$+Au, and ${}^3$He+Au (small systems) collisions as well as $AA$ (large systems) collisions at forward and backward rapidity ($1.2<|y|<2.2$). Comparisons with state-of-the-art theory calculations and LHC data will be discussed. The forward rapidity data in small systems are well described by model calculations for all three systems, however, the backward rapidity $p$+Au and ${}^3$He+Au data are not reproduced by the shadowing calculation alone. $J/\psi$ $v_2$ meausrements in Au+Au collisions at forward rapidity is consistent with zero.
