WIMPs in a 3-3-1 model with heavy Sterile neutrinos
J. K. Mizukoshi, C. A. de S. Pires, F. S. Queiroz +1
In this work we show that from the spectrum of particles of a 3-3-1 gauge model with heavy sterile neutrinos we can have up to three Cold Dark Matter candidates as WIMPs. We obtain…
The Left-Right SU(3)(L)xSU(3)(R)xU(1)(X) Model with Light, keV and Heavy Neutrinos
Alex G. Dias, C. A. de S. Pires, P. S. Rodrigues da Silva
We construct a full left-right model for the electroweak interactions based on the gauge symmetry. The fermion content of the model is…
A minimal 3-3-1 model with naturally sub-eV neutrinos
C. A. de S. Pires, F. Queiroz, P. S. Rodrigues da Silva
In the original version of the minimal SU(3)_C x SU(3)_L x U(1)_N model the masses of all quarks are correctly obtained by introducing three scalar triplets into the model, meanwhi…
Sterile neutrino dark matter, CDMS-II and a light Higgs boson
F. S. Queiroz, C. A. de S. Pires, P. S. Rodrigues da Silva
We add a singlet right handed neutrino plus a charged and a neutral singlet scalars to the standard model. This extension includes a discrete symmetry such that we obtain a heavy s…
Triple seesaw mechanism
D. Cogollo, H. Diniz, C. A. de S. Pires
On fitting the type II seesaw mechanism into the type I seesaw mechanism, we obtain a formula to the neutrino masses which get suppressed by high-scale in its denominator. As…
