Bottomonium Dissociation in a Rotating Plasma

TL;DR

This paper investigates how the rotation of quark-gluon plasma influences the dissociation of bottomonium states using a holographic model, providing insights into the effects of angular momentum on heavy meson stability.

Contribution

It introduces a holographic approach to study the impact of plasma rotation on bottomonium dissociation, an aspect previously less understood in heavy ion collision research.

Findings

Rotation affects bottomonium dissociation rates.

Holographic model captures angular velocity effects.

Results suggest rotation can either stabilize or destabilize mesons.

Abstract

Heavy vector mesons provide important information about the quark gluon plasma (QGP) formed in heavy ion collisions. This happens because the fraction of quarkonium states that are produced depends on the properties of the medium. The intensity of the dissociation process in a plasma is affected by the temperature, the chemical potential and the presence of magnetic fields. These effects have been studied by many authors in the recent years. Another important factor that can affect the dissociation of heavy mesons, and still lacks of a better understanding, is the rotation of the plasma. Non central collisions form a plasma with angular momentum. Here we use a holographic model to investigate the thermal spectrum of bottomonium quasi-states in a rotating medium in order to describe how a non vanishing angular velocity affects the dissociation process.
