Abstract
Heavy quarkonium is a sensitive signature of the new state of matter-quarkgluon plasma produced in high energy nuclear collisions. We describe the spacetime evolution of the quarkgluon 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 semicentral and central collisions and the related transverse momentum suppression at LHC energy.
