Neutrino electromagnetic interactions in elastic neutrino-nucleus scattering

Abstract

The nonzero neutrino masses open the door for neutrino electromagnetic interactions. We study how these interactions may manifest themselves in elastic neutrino-nucleus scattering processes. Following our approach developed for the case of elastic neutrino-electron and neutrino-proton collisions, in our formalism we account for possible electromagnetic form factors of massive neutrinos: the charge, magnetic, electric, and anapole form factors of both diagonal and transition types. We give an illustration of how a nonzero neutrino millicharge can influence the differential cross section of elastic neutrino scattering on a spin-0 nuclear target.
