Nucleon electromagnetic form factors in a quark-gluon core model

TL;DR

This paper models nucleon electromagnetic form factors using a quark-gluon core approach, extending the Isgur-Karl model, and successfully matches experimental data across different momentum transfer ranges.

Contribution

It introduces a novel quark-gluon core model for nucleons that extends existing baryon models and accurately predicts form factors at various Q^2 levels.

Findings

Form factors align with experimental data at low Q^2

Deviations from dipole form at high Q^2 are explained

Model provides a consistent description across momentum ranges

Abstract

We study the nucleon electromagnetic form factors in a quark-gluon core model framework, which can be viewed as an extension of the Isgur-Karl model of baryons. Using this picture we derive nucleon electromagnetic dipole form factors at low Q^2 and the deviation from the dipole form at high Q^2, that are consistent with the existing experimental data.
