Semi-classical approach to $J/\psi$ suppression in high energy heavy-ion collisions

High Energy Physics - Phenomenology 2015-06-18 v1

Abstract

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 ccˉc{\bar c} pair, in a hydrodynamically cooling fireball, to evaluate the total J/ψJ/\psi suppression at both RHIC and LHC energies. Although its limitation is observed, this approach results to a J/ψJ/\psi suppression of around 0.30 at RHIC and 0.25 at LHC.
