TL;DR
This paper explores how future measurements at the planned LHeC collider could significantly improve the accuracy of nuclear parton distribution functions by incorporating simulated data into a global fit, including flavor-specific information.
Contribution
It introduces a method to enhance nuclear PDFs using pseudodata from the LHeC, demonstrating potential improvements over current distributions.
Findings
Nuclear PDFs can be significantly refined with LHeC data.
Flavor-tagged measurements impact the accuracy of PDFs.
Projected data improves understanding of small-x nuclear structure.
Abstract
We study the prospects for constraining the nuclear parton distribution functions by small-x deep inelastic scattering. Performing a global fit of nuclear parton distribution functions including a sample of pseudodata representing expected measurements at the planned LHeC collider, we demonstrate that the accuracy of the present nuclear parton distributions could be be improved substantially. We also discuss the impact of flavour-tagged data.
