| 英文摘要 | We report J/psi spectra for transverse momenta P-T > 5 GeV/c at mid-rapidity in p + p and Au + Au collisions at root s(NN) = 200 GeV. The inclusive J/psi spectrum and the extracted B-hadron feed-down are compared to models incorporating different production mechanisms. We observe significant suppression of the J/psi 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) pi(+/-) and low-p(T) J/psi at RHIC and high-p(T) J/psi at the LHC. (C) 2013 Elsevier B.V. All rights reserved. |
