Discrete Symmetry, Neutrino Magnetic Moment and the 17 Kev Neutrino

Abstract

The problem of generating large transition magnetic moments for nearly massless neutrinos in a truly three--generation case is discussed. A model to achieve the same by exploiting an octahedral symmetry is presented. The scheme also accomodates a radiatively generated mass of $17keV$ for a pseudo--Dirac neutrino that decays rapidly through the Majoron channel.
