Abstract
We report J/Ï spectra for transverse momenta pT>5GeV/c at mid-rapidity in p+p and Au + Au collisions at sNN=200GeV. The inclusive J/Ï spectrum and the extracted B-hadron feed-down are compared to models incorporating different production mechanisms. We observe significant suppression of the J/Ï yields for pT>5GeV/c in 0-30% central Au + Au collisions relative to the p+p yield scaled by the number of binary nucleon-nucleon collisions in Au + Au collisions. In 30-60% mid-central collisions, no such suppression is observed. The level of suppression is consistently less than that of high-pTϱ and low-pTJ/Ï at RHIC and high-pTJ/Ï at the LHC.
