Baryons and Vector Dominance in Holographic Dual QCD

TL;DR

This paper explores how an infinite tower of vector mesons in holographic dual QCD significantly alters the nucleon's soliton structure, restoring vector dominance and potentially impacting hot and dense hadronic matter.

Contribution

It introduces a new perspective on nucleon structure using holographic dual QCD with an infinite vector meson tower, highlighting the restoration of vector dominance.

Findings

Nucleon modeled as a point-like instanton in 5D surrounded by a vector meson cloud.

Infinite vector meson tower restores vector dominance in the model.

Potential implications for hot and dense hadronic matter discussed.

Abstract

The infinite tower of vector mesons encoded in holographic dual QCD bring drastic changes to the soliton structure of the nucleon. The nucleon is given by a point-like instanton in 5D surrounded by a vector meson cloud with the vector dominance restored by the infinite tower. I discuss the possible relevance of this structure in hot and dense hadronic matter.
