Dirac dark matter in a radiative neutrino model

We propose a simple radiative neutrino mass scenario with a Dirac dark matter candidate, which is minimally realized by a Z(3) symmetry. We introduce two Dirac neutrinos and two inert doublets. We demonstrate that the model has a large allowed region that satisfies the constraints from neutrino oscillation data, lepton flavor violations, direct/indirect detection of dark matter and dark matter relic density. We also propose an efficient parameterization of the neutrino Yukawa couplings, which reproduces a desired active neutrino mass matrix. (C) 2020 Elsevier B.V. All rights reserved.

Automated summary

This model proposes a simple radiative neutrino mass scenario with a Dirac dark matter candidate, involving two Dirac neutrinos and two inert doublets. It demonstrates a large allowed region that meets constraints from various sources, and also presents an efficient parameterization for the neutrino Yukawa couplings to reproduce the desired active neutrino mass matrix.
