Holographic picture of heavy vector mesons in a finite density plasma

TL;DR

This paper uses a holographic model to study how heavy vector mesons like bottomonium and charmonium dissociate in a finite temperature and density plasma, revealing how their spectral peaks diminish with increasing temperature and density.

Contribution

It introduces a holographic approach to analyze heavy meson dissociation in a plasma at finite temperature and density, including both bottomonium and charmonium states.

Findings

Spectral peaks decrease with rising temperature and density.

Bottomonium dissociation at finite temperature.

Charmonium dissociation at finite chemical potential.

Abstract

We present the results of a holographic model for heavy vector mesons inside a plasma at finite temperature and density. The spectral function shows a nice description of the dissociation of the mesons in the medium, corresponding to the decrease in the height of the peaks as the temperature and (or) the density increase. We consider the case of bottomonium states at finite temperature and also the case of charmonium dissociation at zero temperature but finite chemical potential.
