A significant suppression of $p_T$-integrated $J/\\psi$ production is observed in central Au+Au events. The Cu+Cu data are consistent with no suppression, although the precision is limited by the available statistics. $R_{AA}$ in Au+Au collisions exhibits a strong suppression at low transverse momentum and gradually increases with $p_T$. The data are compared to high-$p_T$ STAR results and previously published BNL Relativistic Heavy Ion Collider results. Comparing with model calculations, it is found that the invariant yields at low $p_T$ are significantly above hydrodynamic flow predictions but are consistent with models that include color screening and regeneration.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.99158.v1/t1","@type":"Dataset","description":"The invariant yield versus transverse momentum for |y| < 1 in 0-20% centrality in Au+Au collisions (solid circles).
