Parton distribution function nuclear corrections for charged lepton and neutrino deep inelastic scattering processes

Abstract

We perform a ${\ensuremath{\chi}}^{2}$ analysis of nuclear parton distribution functions (NPDFs) using neutral current charged-lepton (${\ensuremath{\ell}}^{\ifmmode\pm\else\textpm\fi{}}A$) 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 (${F}_{2}^{Fe}/{F}_{2}^{D}$) 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.
