Effects of the Transition Magnetic Moment of the Neutrino

Abstract

It is shown that a sizable transition magnetic moment between ${\nu }_{\mu }$ and a massive neutrino ${\nu }^{\prime }$ (of mass of approximately 100 MeV) leads to some detectable effects. These effects could be revealed significantly in ${\nu }_{{\mu }^{-}} \left({\overline{\nu }}_{{\mu }^{-}}\right)$ electron scattering, but would remain hidden in most other cases. It is also pointed out under what circumstances a large transition magnetic moment arises in gauge models.
