摘要
PHENIX has studied J/psi production in root S-NN = 200 GeV collisions of p+p, d+Au,Au+Au and Cu+Cu collisions. This systematic study was designed to allow the extraction of hot nuclear matter effects on J/psi production in heavy ion collisions after accounting for the baseline production cross section using p + p data, and for cold nuclear matter effects using d+Au data. Cold nuclear matter effects, for example gluon shadowing, are the effects associated with production of J/psi from a nuclear target. The large yields obtained in the RHIC 2008 d+Au run provide, for the first time. an opportunity to characterize cold nuclear matter effects at RHIC, and try to isolate hot nuclear matter effects in Au+Au collisions. Low statistics preliminary measurements of excited charmonium yields and gamma(1S + 2S + 3S) yields exist so far for p + p collisions, and there are preliminary results for gamma production in d+Au collisions.
