Findings

Nuclear correction factors for F2(Fe)/F2(D) are extracted and compared.

Differences between charged-lepton and neutrino DIS data are analyzed.

The nuclear A dependence of PDFs is characterized in the fit.

Abstract

We perform a \chi^2-analysis of Nuclear Parton Distribution Functions (NPDFs) using neutral current charged-lepton Deeply Inelastic Scattering (DIS) and Drell-Yan data for several nuclear targets. The nuclear A dependence of the NPDFs is extracted in a next-to-leading order fit. We compare the nuclear corrections factors F2(Fe)/F2(D) for this charged-lepton data with other results from the literature. In particular, we compare and contrast fits based upon the charged-lepton DIS data with those using neutrino-nucleon DIS data.
