Tri-Bimaximal Lepton Mixing and Leptogenesis
D. Aristizabal Sierra, F. Bazzocchi, I. de Medeiros Varzielas +2
In models with flavour symmetries added to the gauge group of the Standard Model the CP-violating asymmetry necessary for leptogenesis may be related with low-energy parameters. A…
Calculable inverse-seesaw neutrino masses in supersymmetry
F. Bazzocchi, D. G. Cerdeno, C. Munoz +1
We provide a scenario where naturally small and calculable neutrino masses arise from a supersymmetry breaking renormalization-group-induced vacuum expectation value. We adopt a mi…
Tri-bi-maximal mixing in viable family symmetry unified model with extended seesaw
Federica Bazzocchi, Ivo de Medeiros Varzielas
We present a Grand Unified model based on SO(10) with a Delta(27) family symmetry. Fermion masses and mixings are fitted and agree well with experimental values. An extended seesaw…
Phenomenological Consequences of See-Saw in S4 Based Models
F. Bazzocchi, L. Merlo, S. Morisi
It was proposed a flavour model based on the symmetry group S4, managing to describe fermion masses and mixings. The Weinberg operator has been used in order to provide the smallne…
Fermion Masses and Mixings in a S4 Based Model
Federica Bazzocchi, Luca Merlo, Stefano Morisi
It has been recently claimed that the symmetry group S4 yields to the Tri-bimaximal neutrino mixing in a "natural" way from the group theory point of view. Approving of this featur…
