Description

Quarkonia breaking in nucleus-nucleus collisions is a powerful tool to probe
density and temperature of the medium created in heavy ion collisions. Forward rapidity measurements in $p(d)$+Au collisions are essential to understand how quarkonia states are affected by initial state effects, formation time, and local particle multiplicity. Earlier measurements in Au+Au collisions showed a stronger suppression of forward J/$\psi$s compared to mid-rapidity results, indicating the
possibility of a smaller contribution of regenerated quarkonia states at forward
rapidity.

This presentation will report on the latest quarkonia studies performed by the
PHENIX collaboration in the rapidity range 1.2$<|y|<$2.2, including (i) the
nucleus size dependence of the J/$\psi$ nuclear modification factor in $p$+Au, $p$+Al and ${}^3$He+Au collisions; (ii) the status of recent analyses of $\mathrm{{\rm Y}}$ states in $p$+$p$, $p$+Au, and in the large statistics 2014 Au+Au data set, the largest data set obtained by PHENIX.
