A Novel Mechanism for $J/\psi$ Disintegration in Relativistic Heavy Ion Collisions

TL;DR

This paper explores how $J/eta$ particles disintegrate in quark-gluon plasma due to $Z(3)$ domain walls, which create localized color electric fields that alter and excite the particles.

Contribution

It introduces a novel mechanism involving $Z(3)$ domain walls causing $J/eta$ disintegration in QGP, a new perspective in heavy ion collision studies.

Findings

$J/eta$ disintegration is facilitated by $Z(3)$ domain walls.

Localized color electric fields induce $J/eta$ excitation and disintegration.

The mechanism explains potential suppression of $J/eta$ in QGP.

Abstract

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.
