Radiative neutrino masses and exotic right-handed neutrinos
A. C. B. Machado, J. Montaño, V. Pleitez +1
We consider an extension of the standard electroweak model with three Higgs doublets and global and symmetries. Two of the scalar doublets are inert due to the…
Charged scalar production at the Compact Linear Collider for the model
G. De Conto, A. C. B. Machado, J. Montaño +1
We present a model with model plus a sterile neutrino and its phenomenological expectations for the production of charged scalars at the Compact Linear C…
Zee and Zee-Babu mechanisms in the minimal 331 model
A. C. B. Machado, Pedro Pasquini, V. Pleitez
We show that the minimal 3-3-1 model cannot accommodate the neutrino masses at tree level using present experimental data. Nevertheless, a modified Zee and the Zee-Babu mechanisms…
Copositivity criteria, scalar mass eigenstates, and custodial symmetry parameter for the model
G. De Conto, A. C. B. Machado
We present the copositivity criteria for the scalar sector of our model, which ensures that it is bounded from below. We also show the scalar mass eigens…
The Higgs boson in the minimal 3-3-1 model
G. De Conto, A. C. B. Machado, J. P. B. C. de Melo
In this paper we present the mass matrices and mass eigenstates for the CP-even neutral scalars in the minimal 331 model (m331) and its self-interactions, showing that the m331 aut…
Analytical solution for the Zee mechanism
A. C. B. Machado, J. Montaño, Pedro Pasquini +1
We found an analytical solution for the neutrino mass matrix in the most general case of the Zee model. Using the recent data on the neutrino parameters besides generating neutrino…
