Radiative Neutrino Mass, Dark Matter and Leptogenesis
arXiv:0712.2933 · doi:10.1103/PhysRevD.77.105031
Abstract
We propose an extension of the standard model, in which neutrinos are Dirac particles and their tiny masses originate from a one-loop radiative diagram. The new fields required by the neutrino mass-generation also accommodate the explanation for the matter-antimatter asymmetry and dark matter in the universe.
