Abstract

PHENIX has measured $\Upsilon$ production in p+p, d+Au and Au+Au collisions at $\sqrt{s_{NN}}$ =200 GeV. A baseline cross-section measurement has been made in p+p collisions. Preliminary studies of d+Au collisions found no suppression in the backward direction, but suppression was observed in the forward direction indicating the presence of cold nuclear matter effects. In Au+Au collisions preliminary studies of $\Upsilon$ production at mid-rapidity found hints of suppression.
