We study the heavy quark/antiquark pair dynamics in strongly-coupled quark
gluon plasma. A semi-classical approach, based on the Wigner distribution and
Langevin dynamics, is applied to a color screened ccˉ pair, in a
hydrodynamically cooling fireball, to evaluate the total J/ψ suppression
at both RHIC and LHC energies. Although its limitation is observed, this
approach results to a J/ψ suppression of around 0.30 at RHIC and 0.25 at
LHC.Comment: 4 pages, 6 figures, Proceeding for International Conference on
