The flavor problem and discrete symmetries
(Elsevier B.V., 2009-04-20)
In this Letter we propose a multi-Higgs extension of the standard model with Abelian and non-Abelian discrete symmetries in which the mass matrices of the charged fermions obtained from renormalizable interactions are ...

Schizophrenic active neutrinos and exotic sterile neutrinos
(Elsevier B.V., 2011-04-04)
We implement a schizophrenic scenario for the active neutrinos in a model in which there are also exotic right-handed neutrinos making a model with a local U(1)(B-L) anomaly free. Two of right-handed neutrinos carry B - L ...

Fermion masses and mixings and dark matter constraints in a model with radiative seesaw mechanism
(2018)
We formulate a predictive model of fermion masses and mixings based on a Delta(27) family symmetry. In the quark sector the model leads to the viable mixing inspired texture where the Cabibbo angle comes from the down quark ...
A rationale for long-lived quarks and leptons at the LHC: low energy flavour theory
(SPRINGERNEW YORK, 2012)
In the framework of gauged flavour symmetries, new fermions in parity symmetric representations of the standard model are generically needed for the compensation of mixed anomalies. The key point is that their masses are ...
Neutral meson mixing induced by box diagrams in the 3-3-1 model with heavy leptons
(Amer Physical Soc, 2015-12-08)
We consider in the 3-3-1 model with heavy leptons the box contributions to the mass difference in K and B neutral mesons induced by neutral (pseudo)scalars, exotic charged quarks, singly and doubly charged scalar and gauge ...
