FIMP dark matter in the scotogenic model at low-reheating temperatures
Robinson Longas, Andrés Rivera, David Suarez
The scotogenic model offers an attractive framework that explains light neutrino masses while accommodating a viable dark matter candidate. In this work, we study the phenomenology…
Multi-component secluded WIMP dark matter and Dirac neutrino masses with an extra Abelian gauge symmetry
Kimy Agudelo, Diego Restrepo, Andrés Rivera +1
Scenarios for secluded WIMP dark matter models have been extensively studied in simplified versions. This paper shows a complete UV realization of a secluded WIMP dark matter model…
Singlet-doublet Dirac fermion dark matter from Peccei-Quinn symmetry
Robinson Longas, Andres Rivera, Cristian Ruiz +1
Weakly Interacting Massive Particles (WIMPs) and axions are arguably the most compelling dark matter (DM) candidates in the literature. Here, we consider a model where the PQ symme…
Dirac dark matter, neutrino masses, and dark baryogenesis
Diego Restrepo, Andrés Rivera, Walter Tangarife
We present a gauged baryon number model as an example of models where all new fermions required to cancel out the anomalies help to solve phenomenological problems of the standard…
Type-II two-Higgs-doublet model in noncommutative geometry
Fredy Jimenez, Diego Restrepo, Andrés Rivera
In noncommutative geometry (NCG) the spectral action principle predicts the standard model (SM) particle masses by constraining the scalar and Yukawa couplings at some heavy scale,…
Lepton dark matter portal in the inert Zee model
Alexandra Gaviria, Robinson Longas, Andrés Rivera
The inert Zee model is an extension of the Zee model for neutrino masses. This new model explains the dark matter relic abundance, generates a one-loop neutrino masses and forbids…
