Elastic Neutrino–Nucleon Scattering and Electromagnetic Properties of Neutrinos

Abstract

We study the electromagnetic contribution to the processes of elastic scattering of neutrinos on nucleons. In our formalism, the electromagnetic charge, magnetic, electric, and anapole form factors of neutrinos, both of diagonal and transition types in the mass basis, are taken into account. When treating the nucleon electromagnetic vertex, we consider not only the charge and magnetic form factors of the nucleon but also its electric and anapole form factors. We analyze the possible effects of the neutrino magnetic moment in the elastic neutrino–nucleon scattering and how they can be distinguished from the effects of strange quarks contributing to the weak neutral current form factor of the nucleon.
