Theory of Deep-Inelastic Lepton-Nucleon Scattering and Lepton Pair Annihilation Processes. IV. Deep-Inelastic Neutrino Scattering

This is the last in a series of four papers devoted to a theoretical study based on canonical field theory of the deep-inelastic lepton processes. In the present paper we present the detailed calculations leading to the limiting behavior---or the "parton model"---for deep-inelastic neutrino scattering, i.e., ν+p→e^-+anything,'' ν+p→e⁺+anything,'' where "anything" refers to all possible hadrons. In particular, we show that the structure functions depend only on the ratio of energy to momentum transfer 2Mνq² as conjectured by Bjorken on general grounds. Experimental implications, including sum rules and the relation of ν and ν cross sections to each other as well as to deep-inelastic electron scattering cross sections, are derived and discussed.
