Neutrino magnetic moment, millicharge and charge radius

Abstract

A brief overview of neutrino electromagnetic properties is presented from a theoretical perspective. Their potential effects on coherent elastic neutrino-nucleus scattering are outlined.

Status and perspectives of neutrino magnetic moments

“…A detailed description of different experiments can be found in [1,20,24,25,26,27]. Here below we focus on the reactor antineutrino experiment since it provides the best nowadays terrestrial laboratory upper limit on the effective neutrino magnetic moment, as well a limit on the neutrino millicharge [38] and probably with the expected improvement of sensitivity will be also sensitive in future to the neutrino charge radius [28].…”

Neutrino-atom collisions

“…Let us consider the case when an electron neutrino scatters on a spin-zero nucleus with even numbers of protons and neutrons, Z and N . The matrix element of this process, taking into account the neutrino electromagnetic properties, reads [44]…”
