Charmonium suppression in the presence of dissipative forces in a strongly coupled quark-gluon plasma

TL;DR

This paper investigates how dissipative forces in a strongly-coupled quark-gluon plasma affect the survival of charmonium states, incorporating first-order dissipative corrections and medium effects, with results aligning with RHIC experiments.

Contribution

It introduces a novel analysis of charmonium suppression considering dissipative effects and medium corrections within a strongly-coupled QGP framework.

Findings

Charmonium survival is sensitive to shear viscosity-to-entropy ratio.

Results agree well with recent RHIC experimental data.

Dissipative corrections significantly impact dissociation temperatures.

Abstract

We study the survival of charmonium states in a strongly-coupled quark-gluon plasma in the presence of dissipative forces. We consider first-order dissipative corrections to the plasma equation of motion in the Bjorken boost-invariant expansion with a strongly-coupled equation of state for QGP and study the survival of these states with the dissociation temperatures obtained by correcting the full Cornell potential not its Coulomb part alone with a dielectric function encoding the effects of deconfined medium. We further explore the sensitivity of prompt and sequential suppression of these states to the shear viscosity-to-entropy density ratio, $\eta/s$ from perturbative QCD and AdS/CFT predictions. Our results show excellent agreement with the recent experimental results at RHIC.
