TL;DR
This paper introduces a modified soft-wall AdS/QCD model with a new dilaton parametrization and cubic scalar potential term, achieving linear confinement and accurate mass spectra for mesons and nucleons while incorporating chiral symmetry breaking.
Contribution
It presents a novel AdS/QCD model that simultaneously realizes linear confinement and chiral symmetry breaking with improved mass spectrum predictions.
Findings
Mass spectra closely match experimental data
Successfully models linear confinement in meson and nucleon sectors
Incorporates chiral symmetry breaking effectively
Abstract
By using a new parametrization of the dilaton field and including a cubic term in the bulk scalar potential, we realize linear confinement in both meson and nucleon sectors within the framework of soft-wall AdS/QCD. At the same time this model also correctly incorporate chiral symmetry breaking. We compare our resulting mass spectra with experimental data and find good agreement between them.
