Elastic neutrino scattering on nuclear systems as a probe of neutrino electromagnetic interactions

TL;DR

This paper investigates how elastic neutrino scattering on nucleons can reveal potential electromagnetic properties of neutrinos, including magnetic moments and electric form factors, by analyzing their effects on scattering processes.

Contribution

It introduces a formalism that incorporates all neutrino electromagnetic form factors and examines their impact on neutrino-nucleon scattering, distinguishing magnetic moments from strange quark effects.

Findings

Electromagnetic form factors influence neutrino scattering observables.

Neutrino magnetic moments can be separated from strange quark contributions.

The formalism provides a comprehensive framework for analyzing neutrino electromagnetic interactions.

Abstract

We study the electromagnetic contribution to elastic neutrino-proton and neutrino-neutron scattering processes. The neutrino electromagnetic charge, magnetic, electric, and anapole form factors of both diagonal and transition types in the mass basis are taken into account in the present formalism. When treating the nucleon electromagnetic vertex, we take into account not only the charge and magnetic form factors of a nucleon, but also its electric and anapole form factors. We examine how the effects of the neutrino magnetic moment can be disentangled from those of the strange quark contributions to the nucleon weak neutral current form factors.
