Consequences of the partial restoration of chiral symmetry in AdS/QCD

TL;DR

This paper explores how partial restoration of chiral symmetry affects physical quantities in an AdS/QCD model, revealing scaling behaviors and proposing a temperature dependence framework within the model.

Contribution

It introduces a novel approach to study partial chiral symmetry restoration effects in AdS/QCD by treating the chiral condensate as a free parameter and incorporating temperature dependence.

Findings

Identified scaling behavior among nucleon mass, pion decay constant, and chiral condensate.

Proposed a phenomenological method for temperature dependence in AdS/QCD models.

Demonstrated effects of partial chiral symmetry restoration on physical quantities.

Abstract

Chiral symmetry is an essential concept in understanding QCD at low energy. We treat the chiral condensate, which measures the spontaneous breaking of chiral symmetry, as a free parameter to investigate the effect of partially restored chiral symmetry on the physical quantities in the frame work of an AdS/QCD model. We observe an interesting scaling behavior among the nucleon mass, pion decay constant and chiral condensate. We propose a phenomenological way to introduce the temperature dependence of a physical quantity in the AdS/QCD model with the thermal AdS metric.
