Proton Structure Functions from an AdS/QCD model with a deformed background

TL;DR

This paper models unpolarized spin 1/2 baryonic deep inelastic scattering using an AdS/QCD approach with a deformed background, successfully matching experimental data for structure functions.

Contribution

It introduces a deformed AdS/QCD model with an exponential factor to incorporate anomalous dimensions, providing a novel theoretical framework for DIS structure functions.

Findings

Structure functions agree with experimental data

Deformed background captures anomalous dimensions

Model extends AdS/QCD applicability to large Bjorken x

Abstract

In this work we study unpolarized spin $1/2$ baryonic deep inelastic scattering (DIS) in the regime of large Bjorken parameter $x$. We calculate the corresponding structure functions $F_{1,2}(x,q^2)$. Our approach is based on an AdS/QCD model with a deformed background, where we consider an exponential factor in the AdS$_5$ metric. Such a deformation implies the introduction of an anomalous dimension in the model. Our results for the structure functions are consistent with those found in the literature from experimental data.
