Electromagnetic Contribution to Scattering of Arbitrarily Polarized Neutrinos on Nucleons

We study theoretically the neutrino electromagnetic interactions in elastic neutrino-nucleon scattering processes. Employing our approach developed earlier for the cases of elastic neutrino-electron and neutrino-proton collisions, we present a general formalism to account for the effects of neutrino flavor and spin oscillations on the source-detector distance. The expressions for the elastic neutrino-nucleon differential cross sections in the case of a mixture of incident left- and right-handed neutrino states are derived.
