Abstract

Heavy quarkonium is a sensitive signature of the new state of matter-quarkgluon plasma produced in high energy nuclear collisions. We describe the spacetime evolution of the quarkgluon plasma by relativistic hydrodynamic equations and the quarkonium motion by transport equation. We found that the competition between the gluon dissociation and regeneration can explain naturally the J/ψ puzzles at RHIC energy. We predict the increase of the nuclear modification factor in semicentral and central collisions and the related transverse momentum suppression at LHC energy.
