We report J/ψ spectra for transverse momenta pT>5GeV/c at mid-rapidity in p+p and Au+Au collisions at sNN=200GeV. 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 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-pT π± and low-pT J/ψ at RHIC and high-pT J/ψ at the LHC. © 2013 Elsevier B.V..
