$\gamma N \to N^*(1535)$ transition in soft-wall AdS/QCD

TL;DR

This paper models the electroexcitation of the $N^*(1535)$ resonance using a soft-wall AdS/QCD approach, successfully matching experimental data for helicity amplitudes.

Contribution

It introduces a novel application of soft-wall AdS/QCD to compute $N^*(1535)$ transition amplitudes, aligning theoretical predictions with experimental observations.

Findings

Good agreement with experimental data for helicity amplitudes

Accurate reproduction of MAID parametrization results

Demonstrates the effectiveness of soft-wall AdS/QCD in baryon resonance studies

Abstract

We present a study of the $N^*(1535)$ resonance electroexcitation in a soft-wall AdS/QCD model. Both the transverse $A_{1/2}^p$ and longitudinal $S_{1/2}^p$ helicity amplitudes are calculated resulting in good agreement with data and with the MAID parametrization.
