Neutral- and charged-current neutrino- and antineutrinonucleon scatterings are analyzed within the GIM picture by accounting for the rather pronounced scaling violations in the weex region and utilizing a parameterξ=〈p ⊥ 2 〉1/2/k. Forx ≫ξ the naive parton model is assumed to apply, whereas forx ≲ξ a diminution of free-partonvs. other scattering is expected. (x andy are the usual scaling variables,k is the c.m. momentum and 〈p ⊥ 2 〉1/2 is the r.m.s. parton transverse momentum ≈ 0.3 GeV.) In the model, an increasing number of sea quarks is freed as the energyE increases and the weex domain recedes towardsx=0. The ratio $$\sigma _c^{\bar \nu \mathcal{N}} /\sigma _c^{\nu \mathcal{N}} , \langle y\rangle _c^{\bar \nu } $$ , inclusive dσ c/dy distributions for νN and $$\bar \nu \mathcal{N}$$ scatterings, neutral-to-charged-current cross-section ratiosR ν and $$R_{\bar \nu } $$ , as well asν-and $$\bar \nu - induced$$ dilepton and accompanying strange-particle production are calculated, leading to satisfactory agreement with experiment from 10 GeV to 150 GeV. In particular, the model implies that $$R_{\bar \nu } (E)$$ remains relatively flat asE increases through the region where $$\sigma _c^{\bar \nu \mathcal{N}} /E$$ appears to rise. Neutral-current processes are calculated by using the charged-current-determined model parameters within the Weinberg-Salam framework with sin2θw=0.3. Comparison with dimuon experiments leads to semi-muonic branching ratios for the decay of charm in the range 5% to 10%, if one assume aSU 3-invariant sea. The calculated mean number of strange particles per neutrino-induced dilepton event is 1.4.
