TL;DR

This paper uses holography to analyze deep inelastic scattering on an extremal RN-AdS black hole, revealing shadowing effects at low Bjorken-x in nuclear structure functions.

Contribution

It introduces a holographic model of a large nucleus as an extremal RN-AdS black hole to study DIS and structure functions.

Findings

Strong shadowing observed at low-x in structure functions

Structure functions mapped to finite large nuclei

Holographic approach provides new insights into nuclear DIS

Abstract

We consider deep inelastic scattering (DIS) on a large nucleus described as an extremal RN-AdS black hole using the holographic principle. Using the R-current correlators we determine the structure functions as a function Bjorken-x, and map it on a finite but large nucleus with fixed atomic number. The R-ratio of the nuclear structure functions exhibit strong shadowing at low-x.
