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 ne utrino magnetic moment and consistent with the phenomenological constr aints on neutrino mass.
