Cold Nuclear Matter Effects and Heavy Quark Production in PHENIX
Abstract
The PHENIX experiment uses semileptonic decay channels to measure open and closed heavy flavor cross sections across the rapidity range -2.2 < y < 2.4. High luminosity data are now available for p+p, d+Au, Cu+Cu and Au+Au collisions at sNN=200 GeV, and for Au+Au collisions at sNN= 62 GeV. We discuss recent d+Au results for open heavy flavor and J/ production, and discuss their implications for the cold nuclear matter contributions to heavy flavor production in heavy ion collisions.
