TL;DR
This paper enhances the soft-wall AdS/QCD model by analyzing meson and nucleon spectra, achieving good agreement with experimental data across various particle types and interactions.
Contribution
It introduces a cubic potential for the bulk scalar in the soft-wall AdS/QCD model and systematically studies meson and nucleon spectra.
Findings
Meson spectra match experimental data well.
Nucleon spectrum aligns with observations.
Pion-nucleon coupling is accurately modeled.
Abstract
We study further the soft-wall AdS/QCD model with a cubic potential for the bulk scalar. We analyze the spectra of pseudoscalar, scalar, vector and axial-vector mesons. We also study the spin-1/2 nucleon spectrum and the pion-nucleon coupling. All of them have a good agreement with the experimental data.
