英文摘要	The measurement of J/psi elliptic flow is presented as a function of transverse momentum for 20%-60% central 200 GeV Au + Au collisions. Total number of reconstructed J/psi used for this measurement is 13,000, which is unprecedented in relativistic heavy ion collisions so far. Extracted value of elliptic flow is found to be consistent with no flow within errors for transverse momentum larger than 2 GeV/c. This suggests that either J/psi with high transverse momentum is dominantly produced by direct pQCD processes, or charm quarks are not fully thermalized in the medium.
