Deviations of exact neutrino textures using radiative neutrino masses
D. Wegman
The Weinberg operator allows for the construction of radiative Majorana neutrino masses. In this letter, it will be shown that it is possible to construct a one-loop diagram that w…
Radiative Two-Loop Neutrino Masses with Dark Matter
C. Simoes, D. Wegman
Using the Weinberg operator, we present a full collection of genuine two-loop models for neutrino mass generation, which contain a dark matter particle as one of the internal messe…
Radiative accidental matter
D. Aristizabal Sierra, C. Simoes, D. Wegman
Accidental matter models are scenarios where the beyond-the-standard model physics preserves all the standard model accidental and approximate symmetries up to a cutoff scale relat…
Closing in on minimal dark matter and radiative neutrino masses
D. Aristizabal Sierra, C. Simoes, D. Wegman
We study one-loop radiative neutrino mass models in which one of the beyond-the-standard model fields is either a hypercharge-zero fermion quintet (minimal dark matter) or a hyperc…
Leptonic CP Violation from a New Perspective
David Emmanuel-Costa, Nuno Rosa Agostinho, J. I. Silva-Marcos +1
We study leptonic CP violation from a new perspective. For Majorana neutrinos, a new parametrization for leptonic mixing of the form reveals inte…
Quasidegeneracy of Majorana Neutrinos and the Origin of Large Leptonic Mixing
G. C. Branco, M. N. Rebelo, J. I. Silva-Marcos +1
We propose that the observed large leptonic mixing may just reflect a quasidegeneracy of three Majorana neutrinos. The limit of exact degeneracy of Majorana neutrinos is not trivia…
