Holographic Meson Spectra in the Dense Medium with Chiral Condensate

TL;DR

This paper investigates how chiral condensate and quark density affect meson spectra in dense media using holographic duality, incorporating 1/Nc corrections through gravitational backreaction in a hard wall model.

Contribution

It introduces a numerical approach to include 1/Nc effects from chiral condensate and quark density in holographic meson spectra analysis.

Findings

Meson spectra are modified by 1/Nc corrections.

Binding energies of heavy quarkonium are affected by dense medium effects.

Dual geometries are obtained for different quark masses.

Abstract

We study two $1/N_c$ effects on the meson spectra by using the AdS/CFT correspondence where the $1/N_c$ corrections from the chiral condensate and the quark density are controlled by the gravitational backreaction of the massive scalar field and U(1) gauge field respectively. The dual geometries with zero and nonzero current quark masses are obtained numerically. We discuss meson spectra and binding energy of heavy quarkonium with the subleading corrections in the hard wall model.
