TL;DR

This paper employs a holographic AdS/QCD model to compute the quark scalar current correlator, aiming to derive QCD-like predictions through physical constraints rather than inverse modeling.

Contribution

It introduces a deformed AdS space holographic model for scalar correlator calculations, emphasizing the importance of physical constraints for predictive QCD results.

Findings

Derived correlator results similar to the soft wall model

Highlighted the role of physical constraints in holographic QCD

Provided a framework for more predictive holographic models

Abstract

We use a holographic model to compute the quark scalar current correlator. Already used in other contexts, our model consists in a bulk field theory defined on a deformed Anti de Sitter space and allows to derive analogous results to those of the soft wall model. One issue of such computations is to understand relevant holographic physical constraints which give predictive QCD results rather than to make the inverse step as done until now.
