Description
The first charm and charmonium data in d+Au collisions at RHIC is beginning to appear. This data offers us a good opportunity to check our basic understanding of hard processes in cold matter at collider energies. While the charm cross section reported by STAR is significantly higher than predicted by NLO calculations, the J/psi cross section reported by PHENIX is in relatively good agreement with the predicted results. The ratio of J/psi production in d+Au relative to pp collisions shows some interesting structure consistent with models of nuclear shadowing and perhaps some weak absorption. We compare our calculations with the open charm and J/psi data.
