Massive Pions, Anomalies and Baryons in Holographic QCD

TL;DR

This paper presents a holographic QCD model that incorporates pion mass, QCD anomalies, and baryons as topological solitons, providing a unified framework with detailed phenomenological analysis.

Contribution

It introduces a simple modification to holographic QCD that simultaneously models pions, anomalies, and baryons, advancing the understanding of their interrelations.

Findings

Model successfully describes pion mass and QCD anomalies.

Baryons are realized as topological solitons within the model.

Phenomenological results align well with experimental observations.

Abstract

We consider a holographic model of QCD, obtained by a very simple modification of the original construction, which describes at the same time the pion mass, the QCD anomalies and the baryons as topological solitons. We study in detail its phenomenological implications in both the mesonic and baryonic sectors and compare with the observations.
