Dark Matter as a Source for Lepton Flavor Violation
Jeremy Echeverria, Patricio Escalona, Farinaldo Queiroz +1
We will witness enormous progress in the experimental sensitivity to charged-lepton-violation processes in the near future. New physics signals of charged lepton violation might be…
Two-Component Dark Matter in the Type-I 2HDM
Patricio Escalona, Jacinto P. Neto, M. J. Neves +2
We investigate a two-component dark matter scenario in the type-I two-Higgs-doublet model. The dark sector contains a real scalar and a Dirac fermion , whose stability is e…
Type I + II Seesaw Model in light of the New Neutrino Oscillation Measurements
Maria Aguilar, Juan Carlos Helo, Toshihiko Ota +3
Global analysis of neutrino oscillation data slightly favors normal mass ordering. In this work, we investigate an extended scalar sector that naturally gives rise to a type I + II…
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…
