Three-flavor quark mass dependence of baryon spectra in holographic QCD

TL;DR

This paper extends the Sakai-Sugimoto holographic QCD model to include strange quark mass effects, calculating baryon spectrum shifts and comparing them with experimental data.

Contribution

It introduces a method to incorporate strange quark mass dependence into the holographic QCD baryon spectra within the Sakai-Sugimoto model.

Findings

Mass shifts qualitatively agree with experimental data

First-order perturbation captures leading quark mass effects

Provides a framework for studying flavor symmetry breaking in holographic QCD

Abstract

We introduce the strange quark mass to the Sakai-Sugimoto model of holographic QCD. We compute mass shifts in the spectra of three-flavor baryons at the leading order in perturbation in quark masses. Comparison with experimental data shows an agreement only qualitatively.
