On two-point correlation functions in AdS/QCD

TL;DR

This paper investigates chiral symmetry breaking in the hard wall AdS/QCD model by solving equations of motion at large momentum, deriving the correlator expansion, and analyzing its dependence on the AdS radius and t'Hooft coupling.

Contribution

It provides an analytical expansion of the left-right correlator in the hard wall AdS/QCD model, linking it to the t'Hooft constant and symmetry breaking measures.

Findings

Derived the first terms of the correlator expansion at large momentum.

Analyzed the dependence of correlator on AdS radius and t'Hooft coupling.

Enhanced understanding of chiral symmetry breaking in holographic QCD models.

Abstract

In this paper we study the chiral symmetry breaking in the hard wall AdS/QCD model. We solve the equations of motion up to the second order at large momentum and obtain the first few terms in the expansion of the "left-right" correlator, which is the measure of symmetry breaking. We study the dependence on AdS radius to get the result as the series in t'Hooft constant.
