Description
We study properties of the quark-gluon plasma from sequential
melting of quarkonia in heavy ion collisions at RHIC and LHC.
A quarkonium travels through the quark gluon fluid and dissociates when
temperature is larger than dissociation temperature which varies among
quarkonium species. Dynamics of the quark gluon fluid is described by
relaticistic hydrodynamics with the latest equation of state from the
lattice QCD simulations. Through comparison of our results with RHIC
data, we constrain the dissociation temperature of J/psi. We also
predict survival probability of quarkonia at high pT at LHC.
