Abstract
STAR collaboration has offered eminent nuclear modification factor of J/psi at high p_T and midrapidity produced in Cu-Cu collisions at \sqrt {s_{NN}}= 200 GeV. Recalling a prediction we can understand that the feature of high-p_T nuclear modification factor is related to c\bar c produced by 2-to-1 and 2-to-2 partonic processes in deconfined matter particularly in the prethermal stage and to the recombination of c and \bar c. The nuclear modification factor at high p_T is sensitive to the earliest form of deconfined matter that does not have a temperature.
