摘要：

The STAR Collaboration has offered an eminent nuclear modification factor of J/ψ at high p T and midrapidity produced in Cu-Cu collisions at sNN= 200 GeV. Recalling a prediction, we can understand that the feature of high-pT nuclear modification factor is related to cc produced by 2 → 1 and 2 → 2 partonic processes in deconfined matter, particularly in the prethermal stage and to the recombination of c and c. The nuclear modification factor at high p T is sensitive to the earliest form of deconfined matter that does not have a temperature.
