An SU(5)Z_{13} Grand Unification Model
Alex G. Dias, Edison T. Franco, Vicente Pleitez
We propose an SU(5) grand unified model with an invisible axion and the unification of the three coupling constants which is in agreement with the values, at , of , ,…
Left-right asymmetries, the weak mixing angle, and new physics
J. C. Montero, V. Pleitez, M. C. Rodriguez
The goal of this article is to outline the advantages of the measurement of left-right asymmetries in lepton-lepton () scattering for performing precision…
Realistic extremely flat scalar potential in 3-3-1 models
Alex G. Dias, V. Pleitez, M. D. Tonasse
We show that in 3-3-1 models it is possible to implement an extremely flat scalar potential, i.e., a zero contribution to the cosmological constant, and still having realistic valu…
Neutrino-neutrino and neutrino-matter helicity flip interactions
Vicente Pleitez
Taking into account that neutrinos are massive particles and that they are produced mainly as states of negative helicity, we show that the neutral and charged current interactions…
MSW effect with flavor changing interactions and the atmospheric neutrino problem
J. C. Montero, V. Pleitez
We consider flavor changing effective neutrino interactions in the context of massive neutrinos in the issue of atmospheric neutrinos. Assuming as usual that this is an indication…
Direct CP violation in semi-leptonic and leptonic decays
V. Pleitez
We show that direct CP violation in semi-leptonic and leptonic decays can occur in multi-Higgs doublet extensions of the electroweak standard model with flavor changing neutral cur…
