Deep inelastic scattering of baryons in a modified soft wall model

TL;DR

This paper uses a modified soft wall AdS/QCD model with dressed bulk fermion masses to calculate baryon structure functions in deep inelastic scattering, comparing results with experimental data at high Bjorken x.

Contribution

It introduces a dressed mass for bulk fermionic fields in the soft wall model to improve the calculation of baryon structure functions.

Findings

The model's proton structure function $F_2$ aligns with experimental data at large x.

The approach provides a new way to incorporate fermion mass effects in holographic QCD.

Results suggest improved accuracy over previous models in the high-x regime.

Abstract

We calculate the structure functions for unpolarized deep inelastic scattering of baryons using an AdS/QCD soft wall model that considers a dressed mass for the bulk fermionic fields. Considering the regime of large Bjorken parameter x, we compare the results for the proton structure function $F_2$ with experimental results.
