Nuclear Corrections and Parton Distribution Functions—Lessons Learned from Global Fitting

The effects of adding new data sets for neutrino and antineutrino deep inelastic scattering and dimuon production in pp and pd scattering to global fits for parton distribution functions are presented. Particular emphasis is placed on the effects at large x. The role of nuclear corrections in describing the neutrino and antineutrino data is also discussed.
