Update and Comparison of Nuclear Parton Distribution Functions and Neutrino DIS

TL;DR

This paper compares nuclear correction factors derived from neutrino DIS data with those from standard nuclear PDF analyses, highlighting discrepancies especially with NuTeV data.

Contribution

It provides a detailed comparison of nuclear correction factors from neutrino and charged lepton data, addressing inconsistencies in the field.

Findings

Discrepancies identified between neutrino and charged lepton nuclear corrections.

NuTeV neutrino DIS data shows significant deviation from standard nuclear PDFs.

Highlights need for refined models to reconcile different data sources.

Abstract

We compare the nuclear corrections factors from neutrino deep-inelastic scattering (DIS) with the ones coming from a standard analysis of nuclear parton distribution functions (nPDF). We focus on a discrepancy between the most precise neutrino DIS data from NuTeV and the nuclear PDF coming from the analysis of charged lepton DIS and Drell-Yan data.
