A Novel Mechanism for $J/\psi$ Disintegration in Relativistic Heavy Ion Collisions
In this paper we discuss the possibility of $J/\psi$ disintegration due the $Z(3)$ domain walls that are expected to form in QGP medium. These domain walls give rise to localised color electric field which disintegrates $J/\psi$, on interaction, by changing the color composition and simultaneously exciting it to higher states of $c\bar{c}$ system.
