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 …
Diboson anomaly: heavy Higgs resonance and QCD vector-like exotics
D. Aristizabal Sierra, J. Herrero-Garcia, D. Restrepo +1
The ATLAS collaboration (and also CMS) has recently reported an excess over Standard Model expectations for gauge boson pair production in the invariant mass region TeV.…
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…
