Nuclear parton distributions and deviations from DGLAP at an Electron Ion Collider

TL;DR

This paper investigates how an Electron Ion Collider can precisely measure nuclear modifications of parton distribution functions, especially gluon shadowing, and explore non-linear QCD effects at very small x values.

Contribution

It demonstrates the collider's capability to accurately measure gluon shadowing and detect non-linear QCD phenomena in nuclear PDFs.

Findings

Gluon shadowing can be measured down to x=0.001

Potential to detect non-linear QCD effects with inclusive measurements

Highlights the collider's role in understanding nuclear parton distributions

Abstract

We explore the potential of an Electron Ion Collider to determine nuclear modifications of PDFs. We find that gluon shadowing can be accurately measured down to x=0.001, and discuss the possibility of detecting non--linear QCD effects with inclusive measurements.
