Nuclear shadowing at low Q^2

TL;DR

This paper investigates nuclear shadowing at low Q^2, showing that models combining vector meson dominance and partonic mechanisms align well with experimental data on shadowing effects.

Contribution

It demonstrates that hybrid models including vector meson and partonic effects accurately describe nuclear shadowing at low Q^2.

Findings

Models with both vector meson and partonic mechanisms match data

The Q^2 dependence of shadowing is well explained by these models

The magnitude of shadowing is consistent with experimental observations

Abstract

We re-examine the role of vector meson dominance in nuclear shadowing at low Q^2. We find that models which incorporate both vector meson and partonic mechanisms are consistent with both the magnitude and the Q^2 slope of the shadowing data.
