Neutrino masses through see-saw mechanism in 3-3-1 models
J. C. Montero, C. A. de S. Pires, V. Pleitez
Some years ago it was shown by Ma that in the context of the electroweak standard model there are, at the tree level, only three ways to generate small neutrino masses by the see-s…
Lepton Masses from a TeV Scale in a 3-3-1 Model
J. C. Montero, C. A. de S. Pires, V. Pleitez
In this work, using the fact that in 3-3-1 models the same leptonic bilinear contributes to the masses of both charged leptons and neutrinos, we develop an effective operator mecha…
Electric charge quantization and the muon anomalous magnetic moment
C. A. de S. Pires, P. S. Rodrigues da Silva
We investigate some proposals to solve the electric charge quantization puzzle, which simultaneously explain the recent measured deviation on the muon anomalous magnetic moment. Fo…
Small Active and Sterile Neutrino Masses from the TeV Scale
A. Pérez-Lorenzana, C. A. de S. Pires
A new mechanism for understanding small neutrino masses using only simple new physics at the TeV scale is proposed. As an application, it is shown how it can naturally lead to the…
Seesaw tau lepton mass and calculable neutrino masses in a 3-3-1 model
J. C. Montero, C. A. de S. Pires, V. Pleitez
In a version of the 3-3-1 model proposed by Duong and Ma the introduction of the scalar sextet for giving mass to the charged leptons is avoided by adding a singlet charged lepton.…
Scalar scenarios contributing to (g-2)_mu with enhanced Yukawa couplings
C. A. de S. Pires, P. S. Rodrigues da Silva
In this work we address contributions from scalars to (g-2)_μ. In order to explain the recently measured deviation by the BNL experiment on (g-2)_μ, it is necessary that these scal…
