The Inert Zee Model
Robinson Longas, Dilia Portillo, Diego Restrepo +1
We study a realization of the topology of the Zee model for the generation of neutrino masses at one-loop with a minimal set of vector-like fermions. After imposing an exact …
Fermion dark matter from SO(10)
Carolina Arbelaez, Robinson Longas, Diego Restrepo +1
We construct and analyze nonsupersymmetric SO(10) standard model extensions which explain dark matter (DM) through the fermionic Higgs portal. In these SO(10)-based models the DM p…
Radiative neutrino masses in the singlet-doublet fermion dark matter model with scalar singlets
Diego Restrepo, Andrés Rivera, Marta Sánchez-Peláez +2
When the singlet-doublet fermion dark matter model is extended with additional --odd real singlet scalars, neutrino masses and mixings can be generated at one-loop level. In t…
