          Abstract

          In this work we demonstrate how Scotogenic model can arise naturally from an \(SU(7)\) grand unified theory. Our model also includes a low scale Pati-Salam \(SU(4)_c\times SU(2)_L\times U(1)_R\) symmetry which unifies quarks and leptons. \(\mathbb{Z}_2\) symmetry needed for the realization of Scotogenic scenario is a residual symmetry and not \(ad\) \(hoc\). A short fermion masses and dark matter analysis is included.

            Verifiable Radiative Seesaw Mechanism of Neutrino Mass and Dark Matter

            Ernest Ma (2006)
            A minimal extension of the Standard Model is proposed, where the observed left-handed neutrinos obtain naturally small Majorana masses from a one-loop radiative seesaw mechanism. This model has two candidates (one bosonic and one fermionic) for the dark matter of the Universe. It has a very simple structure and should be verifiable in forthcoming experiments at the Large Hadron Collider.

              Pathways to Naturally Small Neutrino Masses

              Ernest Ma (1998)
              In the minimal standard electroweak gauge model, there is an effective dimension-five operator which generates neutrino masses, and it has only three tree-level realizations. One is the canonical seesaw mechanism with a right-handed neutrino. Another is having a heavy Higgs triplet as recently proposed. The third is to have a heavy Majorana fermion triplet, an example of which is presented here in the context of supersymmetric SU(5) grand unification. The three generic one-loop realizations of this operator are also discussed.
