Abstract

I present here a new Glauber-inspired approach to derive normal cold nuclear matter effects on J/ψ production in Au-Au collisions. In an as much as possible model-independent way, it extrapolates the centrality-dependent yields from d-Au to Au-Au collisions. I then compare the new Au-Au measurements shown by the PHENIX experiment in this conference. In the most central collisions, J/ψ survival probabilities beyond cold nuclear matter effects are found to be 44 23% at forward (y ≤ 1.7) and 25 12% at mid (y ≤ 0) rapidities.
