Thermal dissociation of heavy mesons and configurational entropy

TL;DR

This paper investigates how the configurational entropy can be used to analyze the stability and dissociation of heavy mesons like bottomonium and charmonium in a thermal medium using a holographic AdS/QCD model.

Contribution

It introduces the use of configurational entropy to study heavy meson dissociation in a thermal medium within a holographic framework, providing a new perspective on meson stability.

Findings

Configurational entropy increases with temperature, indicating reduced meson stability.

The model successfully describes quasinormal modes for heavy mesons in a plasma.

CE serves as a useful tool to predict meson dissociation thresholds.

Abstract

We study the dissociation of heavy vector mesons in a thermal medium from the point of view of the configurational entropy. Bottomonium and charmonium vector mesons in a plasma are represented using a holographic AdS/QCD model. The quasinormal modes, describing the quasiparticle states, are determined for a representative range of temperature and the corresponding CE is then computed. The main result indicates that the CE is an important contrivance to investigate the stability of the heavy mesons against dissociation in the thermal medium.
