Deep Inelastic Scattering on a Nucleus using Holography

TL;DR

This paper uses holography to estimate nuclear structure functions in deep inelastic scattering, focusing on the large-x regime and comparing results with experimental data.

Contribution

It introduces a holographic approach to model nuclear DIS structure functions based on a density expansion and incoherent scattering on nucleons.

Findings

Holographic structure functions provide a non-perturbative estimate of nuclear structure functions.

Results agree with experimental data in the large-x regime.

Incoherent scattering dominates at leading order in the density.

Abstract

We consider deep inelastic scattering (DIS) on a nucleus described using a density expansion. In leading order, the scattering is dominated by the incoherent scattering on individual nucleons distributed using the Thomas-Fermi approximation. We use the holographic structure functions for DIS scattering on single nucleons to make a non-perturbative estimate of the nuclear structure function in leading order in the density. Our results are compared to the data in the large-x regime.
