Form factors and transverse charge and magnetization densities in the hard-wall AdS/QCD model

TL;DR

This paper investigates nucleon flavor form factors and transverse charge and magnetization densities using a hard-wall AdS/QCD model, comparing results with experimental data and phenomenological parametrizations.

Contribution

It introduces a detailed analysis of flavor structures in nucleons within the hard-wall AdS/QCD framework, including polarized cases, and compares with experimental and phenomenological models.

Findings

AdS/QCD results agree with experimental data for flavor form factors.

Detailed flavor charge and magnetization densities are obtained for polarized nucleons.

Comparison shows strengths and limitations of the hard-wall AdS/QCD model.

Abstract

We present a study of the flavor form factors in the framework of a hard-wall AdS/QCD model and compare with the available experimental data. We obtain the flavor form factors by decomposing the Dirac and Pauli form factors for the nucleons using the charge and isospin symmetry. Further, we present a detailed study of the flavor structures of the charge and anomalous magnetization densities in the transverse plane. Both the unpolarized and the transversely polarized nucleons are considered here. We compare the AdS/QCD results with two standard phenomenological parametrizations.
