Neutrino Electromagnetic Properties in Elastic Neutrino–Proton Scattering

The contribution of neutrino electromagnetic properties to elastic neutrino–proton scattering is considered in detail. The neutrino electromagnetic properties are introduced via the charge, magnetic, electric, and anapole form factors in the basis of neutrino mass eigenstates. The effects of mixing of three neutrino states are taken into account along with effects of the change in the flavor of a neutrino that moves from the source to the detector. The weak neutral and electromagnetic nucleon form factors are also taken into account. The differential cross section calculated numerically for elastic neutrino–proton scattering obtained with allowance for the neutrino charge radius and magnetic moment are compared with the predictions of the Standard Model for reactor and accelerator neutrinos.
