N2 - The nucleon sea parton distributions probed by muons and neutrinos are different since excitation of ss, cc pairs by muons and cs, sc pairs by neutrinos have different mass thresholds. Natural starting points for the structure functions are cv(x, Q2) ≈ sv(x, Q2), in v (v) interactions and cμ(x,Q2) ≪ s μ(x, Q2) in μ interactions. Up to ∼ 20% corrections to the conventional predictions for the neutrino structure functions at small x are predicted. The effects we discuss are in leading twist and persist numerically up to large values of Q2.
