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…
Combining texture zeros with a remnant CP symmetry in the minimal type-I seesaw
D. M. Barreiros, R. G. Felipe, F. R. Joaquim
In the framework of the two right-handed neutrino seesaw model, we consider maximally-restrictive texture-zero patterns for the lepton Yukawa coupling and mass matrices, together w…
The minimal type-I seesaw model with maximally-restricted texture zeros
D. M. Barreiros, R. G. Felipe, F. R. Joaquim
In the context of Standard Model (SM) extensions, the seesaw mechanism provides the most natural explanation for the smallness of neutrino masses. In this work we consider the most…
