Abstract

We perform a $χ^{2}$ analysis of nuclear parton distribution functions (NPDFs) using neutral current charged-lepton ( $ℓ^{\pm} A$ ) 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 ( $F_{2}^{F e} / F_{2}^{D}$ ) 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.
