We report J / ψ spectra for transverse momenta p T > 5 GeV / c at mid-rapidity in p + p and Au + Au collisions at s NN = 200 GeV . The inclusive J / ψ spectrum and the extracted B-hadron feed-down are compared to models incorporating different production mechanisms. We observe significant suppression of the J / ψ yields for p T > 5 GeV / 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- p T π ± and low- p T J / ψ at RHIC and high- p T J / ψ at the LHC.
