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 accommodates a radiatively generated mass of 17 keV for a pseudo Dirac neutrino that decays rapidly through the Majoron channel.
