Hybrid scoto/seesaw: flavour and dark matter
D. M. Barreiros, H. B. Câmara, F. R. Joaquim
We propose a model based on the interplay between the type-II seesaw and scotogenic neutrino mass generation mechanisms. The setup features a discrete flavour symmet…
Scalar-singlet assisted leptogenesis with CP violation from the vacuum
D. M. Barreiros, H. B. Câmara, R. G. Felipe +1
In the vanilla type-I seesaw leptogenesis scenario, CP violation required to generate the lepton asymmetries in the heavy Majorana neutrino decays stem from complex Dirac-type Yuka…
Flavour and dark matter in a scoto/type-II seesaw model
D. M. Barreiros, H. B. Camara, F. R. Joaquim
The neutrino mass and dark matter (DM) problems are addressed in a Standard Model extension where the type-II seesaw and scotogenic mechanisms coexist. The model features a flavour…
Quantum gravity phenomenology at the dawn of the multi-messenger era -- A review
A. Addazi, J. Alvarez-Muniz, R. Alves Batista +157
The exploration of the universe has recently entered a new era thanks to the multi-messenger paradigm, characterized by a continuous increase in the quantity and quality of experim…
Minimal scoto-seesaw mechanism with spontaneous CP violation
D. M. Barreiros, F. R. Joaquim, R. Srivastava +1
We propose simple scoto-seesaw models to account for dark matter and neutrino masses with spontaneous CP violation. This is achieved with a single horizontal discre…
New approach to neutrino masses and leptogenesis with Occam's razor
D. M. Barreiros, F. R. Joaquim, T. T. Yanagida
The minimal type-I seesaw framework with texture-zero Yukawa and mass matrices inspired by Occam's razor is incompatible with normally-ordered neutrino masses (currently preferred…
