# Electromagnetic stress on nucleon structure

## TL;DR

This paper explores how external electromagnetic fields induce stress on nucleons, affecting their internal structure, and proposes models to describe the charge dependence of the EMC effect in nuclei.

## Contribution

It introduces a simple model linking electromagnetic stress to the EMC effect and validates it with explicit models for different nuclear sizes.

## Key findings

- The model explains charge dependence of the EMC effect.
- Continuous and discrete models are effective for large and small nuclei.
- Results align with experimental observations.

## Abstract

External electromagnetic fields can provoke stress, and thus modifications of the internal structure of nucleons. Working with this hypothesis, one can derive a simple description of the charge dependence of the EMC effect. This first result is confirmed by two explicit models of the structure functions of deformed nucleons in the atomic nucleus. For large nuclei a continuous model is used. For small nuclei a discrete distribution of nuclear matter gives better results.
