Novel mechanism for J /ψ disintegration in relativistic heavy ion collisions
In this paper we discuss the possibility of $J/\ensuremath{\psi}$ disintegration due to $Z(3)$ domain walls that are expected to form in a QGP medium. These domain walls give rise to a localized color electric field, which disintegrates $J/\ensuremath{\psi}$, on interaction, by changing its color composition and simultaneously exciting it to higher states of $c\overline{c}$ system.
