Large degeneracy in light mesons from a modified soft-wall holographic model

TL;DR

This paper introduces a modified soft-wall holographic model combined with light-front holographic QCD to explain the observed degeneracy in light meson spectra, providing a theoretical framework for this phenomenon.

Contribution

The paper presents a novel modification to the soft-wall holographic model that reproduces the hydrogen-like degeneracy observed in light meson spectra.

Findings

Reproduces experimental degeneracy patterns in light mesons

Provides a theoretical basis for meson spectrum degeneracy

Integrates holographic models with light-front QCD

Abstract

We propose a modification of soft-wall holographic model that in combination with the light-front holographic QCD leads to a broad hydrogen-like degeneracy of the same sort as the degeneracy observed experimentally in the spectrum of light mesons.
