- Description
- The deep inelastic scattering of neutrinos on unpolarized nucleons is considered in a generalized parton model which takes into account quark-clustering effects, modeled by diquarks. The diquark contributions are expected to be significant at small <math>Q^2</math> values and to vanish asymptotically, and describe phenomenologically higher-twist corrections. The most general case is studied, which includes both scalar and pseudo-vector diquarks inside the nucleons, as well as the contribution of scalar-vector and vector-scalar transitions. The resulting scaling violations are briefly discussed.
