The seesaw mechanism at TeV scale in the 3-3-1 model with right-handed neutrinos
D. Cogollo, H. Diniz, C. A. de S. Pires +1
We implement the seesaw mechanism in the 3-3-1 model with right-handed neutrinos. This is accomplished by the introduction of a scalar sextet into the model and the spontaneous vio…
Fermion family number and the Z-Z mixing in the 3-3-1 model with right-handed neutrinos
D. Cogollo, H. Diniz, C. A. de S. Pires +1
Theoretical consistency of the 3-3-1 model with right-handed neutrinos demands that the number of family of fermions be exactly equal to three. In this brief report we show that su…
Invisible Z decay width bounds on active-sterile neutrino mixing in the (3+1) and (3+2) models
C. A. de S. Pires
In this work we consider the standard model extended with singlet sterile neutrinos with mass in the eV range and mixed with the active neutrinos. The active-sterile neutrino mixin…
Spontaneous CP violation in the 3-3-1 model with right-handed neutrinos
A. Doff, C. A. de S. Pires, P. S. Rodrigues da Silva
We implement the mechanism of spontaneous CP violation in the 3-3-1 model with right-handed neutrinos and recognize their sources of CP violation. Our main result is that the mecha…
Explicitly broken lepton number at low energy in the Higgs triplet model
C. A. de S. Pires
We suppose that lepton number is explicitly broken at low energy scale(M) in the framework of the Higgs triplet() model. The scalar sector of the model is developed considering…
Naturally light right-handed neutrinos in a 3-3-1 Model
Alex G. Dias, C. A. de S. Pires, P. S. Rodrigues da Silva
In this work we show that light right-handed neutrinos, with mass in the sub-eV scale, is a natural outcome in a 3-3-1 model. By considering effective dimension five operators, the…
