J/ψ-dissociation by a color electric flux tube

Abstract

We adress the question of how a $c-\bar{c}$-state (a $J/ψ$) can be dissociated by the strong color electric fields when moving through a color electric flux tube. The color electric flux tube and the dissociation of the heavy quarkonia state are both described within the Friedberg-Lee color dielectric model. We speculate on the importance of such an effect with respect to the observed $J/ψ$-suppression in ultrarelativistic heavy ion collisions.
