Abstract
Assuming scaling of the nucleon structure functions, we derive relations for the y-distributions in deep inelastic neutrino scattering for the most general local interaction of neutrinos with hadrons via neutral currents with V, A, S, P and T pieces. In addition, optimal bounds for the y-distributions are presented which follow from positivity requirements for the structure functions and which may serve to discriminate between pure V, A currents and the presence of S, P, T couplings. The influence of the predictions of the spin- 1 2 parton model on the bounds is investigated. All relations and bounds depend only on the ratio of total neutrino and antineutrino cross sections.
