Mesons and nucleons from holographic QCD

TL;DR

This paper proposes a unified holographic QCD model treating mesons and nucleons equally using a hard-wall approach, addressing theoretical inconsistencies and suggesting improvements with a five-dimensional anomalous dimension.

Contribution

It introduces a unified framework in AdS/QCD that treats mesons and nucleons consistently, resolving previous model inconsistencies.

Findings

Resolved a theoretical inconsistency in existing models

Unified treatment of mesons and nucleons using the same IR cutoff

Suggested enhancement with a five-dimensional anomalous dimension

Abstract

We present in this talk a recent investigation on a unified approach within the framework of a hard-wall model of AdS/QCD. We first study a theoretical inconsistency in existing models. In order to remove this inconsistency, we propose a unified approach in which the mesons and the nucleons are treated on the same footing, the same infrared (IR) cutoff being employed in both fermionic and bosonic sectors. We also suggest a possible way of improving the model by introducing a five-dimensional anomalous dimension.
