Nuclear parton distribution functions

We study nuclear effects of charged current deep inelastic neutrino-iron scattering in the framework of a X2 analysis of parton distribution functions (PDFs). A set of iron PDFs are extracted and used to compute xBj-dependent and Q2-dependent nuclear correction factors which are required in global analyses of free nucleon PDFs. We compare our results with nuclear correction factors from neutrino-nucleus scattering models and correction factors for ℓ±-iron scattering. Except for very high xBj, our correction factors differ in both shape and magnitude from the correction factors of the models and charged-lepton scattering.
