Scientific paper

It is pointed out that the radiative-neutrino-decay mechanism proposed by Fukugita (1988) to explain the observed excess microwave background radiation can be naturally realized in a class of gauge models where the primary decay mode of the heavy neutrino is nu(H)-3nu(e) with a radiative branching ratio B(nu/H/-nu/e/ + gamma) = 0.0001-0.00001. These models also provide a natural understanding of the smallness of the neutrino masses via the seesaw mechanism. Constraints from muon-decay experiments require the existence of a light Higgs particle with M(H) below 100 GeV which couples dominantly to the neutrinos.
