In-medium hadronic spectral functions through the soft-wall holographic model of QCD

TL;DR

This paper investigates how scalar glueball and vector meson spectral functions change in hot and dense media using a holographic QCD model, providing insights into hadron behavior under extreme conditions.

Contribution

It introduces a holographic approach to study in-medium hadronic spectral functions at finite temperature and density, extending previous models with the AdS/RN metric.

Findings

Hadron masses decrease with increasing temperature and density.

Widths of hadronic states increase, indicating broadening in medium.

Results align with some experimental data and other theoretical models.

Abstract

We study the scalar glueball and vector meson spectral functions in a hot and dense medium by means of the soft-wall holographic model of QCD. Finite temperature and density effects are implemented through the AdS/RN metric. We analyse the behaviour of the hadron masses and widths in the $(T,\mu)$ plane, and compare our results with the experimental ones and with other theoretical determinations.
