Recall a Prediction on J/psi Nuclear Modification Factor for STAR Measurements
Abstract
STAR collaboration has offered eminent nuclear modification factor of J/psi at high pT 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 c 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 c. The nuclear modification factor at high pT is sensitive to the earliest form of deconfined matter that does not have a temperature.
