Abstract:
Two-loop contributions to Majorana mass and transition magnetic moment in a gauge model not in conflict with decaying neutrino
dark matter (DDM) hypothesis have been studied. Another variant of an earlier model J Dhar and S Dev,Pramana — J. Phys.39 541 (1992)] consistent with the DDM hypothesis is proposed and is shown to lead to large enough neutrino magnetic moment
and consistent with the phenomenological constraints on neutrino mass.
