Nuclear shadowing in deep inelastic scattering on nuclei at low and medium Q^2

TL;DR

This paper calculates nuclear shadowing effects in deep inelastic scattering at low x and Q^2 using a two-component model, comparing results with experimental data.

Contribution

It introduces a two-component approach combining generalized VMD and the hard pomeron within the colour dipole model to describe nuclear shadowing.

Findings

Numerical shadowing corrections agree with E665 and NMC data.

Shadowing effects are significant at low x and Q^2.

The model effectively describes virtual photon-nucleon interactions.

Abstract

Nuclear shadowing corrections to the structure functions of deep inelastic scattering of intermediate-mass nuclei are calculated at very low values of Bjorken x and small values of Q^2 (Q^2<5 GeV^2). The two-component approach (generalized VMD plus hard pomeron) is used for a description of the underlying virtual photon - nucleon interaction. The hard component of the nucleon structure function is calculated in a framework of the colour dipole model with dipole cross section having Regge-type energy dependence. Numerical results for nuclear shadowing corrections are compared with available data of E665 and NMC collaborations.
