Gluon saturation effects on J/Psi production in heavy ion collisions

TL;DR

This paper investigates how gluon saturation in heavy ion collisions affects J/Psi production, showing it as a key factor in suppression patterns and explaining experimental observations.

Contribution

It introduces a novel mechanism linking gluon saturation to J/Psi suppression, providing a new perspective on nuclear collision dynamics.

Findings

Gluon saturation significantly suppresses J/Psi production.

The mechanism explains rapidity dependence of suppression.

The model aligns with experimental data.

Abstract

We discuss a novel mechanism for J/Psi$ production in nuclear collisions arising due to the high density of gluons. We demonstrate that gluon saturation in the colliding nuclei is a dominant source of J/Psi suppression and can explain its experimentally observed rapidity and centrality dependence.
