# The Self-energy of Nucleon in the Pseudovector Coupling Pion-nucleon System for the Electromagnetic Form Factor of Proton

## TL;DR

This paper investigates the proton's electromagnetic form factor using a pseudovector pion-nucleon coupling model, incorporating non-perturbative effects to improve the understanding of its $Q^2$ dependence.

## Contribution

It introduces a non-perturbative correction to the pseudovector coupling model to better describe the proton's electromagnetic form factor.

## Key findings

- Improved $Q^2$ dependence matches experimental data
- Enhanced understanding of nucleon self-energy effects
- Refined theoretical model for proton structure

## Abstract

The electromagnetic form factor of proton is studied following our previous calculation of the anomalous magnetic moment. The non-perturbative term is incorporated to correct the $Q^2$ dependence.
