# Structure Functions of the Nucleon in a Soliton Model

## TL;DR

This paper investigates the nucleon structure functions within a soliton model based on the bosonized Nambu-Jona-Lasinio framework, analyzing the significance of vacuum versus valence quark contributions.

## Contribution

It introduces a detailed analysis of vacuum and valence quark contributions to nucleon structure functions in a soliton-based Nambu-Jona-Lasinio model.

## Key findings

- Vacuum contributions are significant in the structure functions.
- Valence quark contributions are comparable or smaller than vacuum contributions.
- The study clarifies the role of vacuum effects in nucleon structure.

## Abstract

We study nucleon structure functions in the soliton picture of the bosonized Nambu-Jona-Lasinio model. We focus on their vacuum contributions and examine whether they are outweighed by their valence quark counterparts.
