Tensorial charge assignments in unitary groups
E. Castillo-Ruiz, Henry Diaz, V. Pleitez
We present an index-based tensorial formulation for computing eigenvalues of charge operators acting on arbitrary tensor representations of unitary gauge groups. The construction f…
The number of fundamental constants from a spacetime-based perspective
George E. A. Matsas, Vicente Pleitez, Alberto Saa +1
We revisit Duff, Okun, and Veneziano's divergent views on the number of fundamental constants and argue that the issue can be set to rest by having spacetime as the starting point.…
Effects of new physics on the Standard Model parameters and vice versa
Mario W. Barela, V. Pleitez
This note discusses the matter of probing Beyond the Standard Model physics and how, to succeed in this quest, the interpretations of the Standard Model regarding observed phenomen…
Global Analysis of the post-SNO Solar Neutrino Data for Standard and Non-Standard Oscillation Mechanisms
A. M. Gago, M. M. Guzzo, P. C. de Holanda +4
What can we learn from solar neutrino observations? Is there any solution to the solar neutrino anomaly which is favored by the present experimental panorama? After SNO results, is…
Adiabatic matter effect with three generation neutrinos and the solar neutrino problem
M. M. Guzzo, O. L. G. Peres, V. Pleitez +1
We find an exact analytic solution for the time evolution of a three Dirac neutrino system adiabatically oscillating in matter, constructing explicitly the relevant mix…
Three generation vacuum oscillations and the solar neutrino problem
M. M. Guzzo, O. L. G. Peres, V. Pleitez +1
We investigate the solar neutrino problem in the scenario of three generation neutrino oscillation hypothesis, taking into account other phenomenological constraints to the neutrin…
Some consequences in weak processes of three generations mixing in the leptonic sector
O. L. G. Peres, V. Pleitez, R. Zukanovich Funchal
We investigate the sensitivity of some weak processes to a Cabibbo--Kobayashi--Maskawa mixing in the leptonic sector. Values for mixing angles and masses compatible with several ex…
Radiatively induced electron and electron-neutrino masses
F. Pisano, V. Pleitez, M. D. Tonasse
We consider, in the context of a 331 model with a single neutral right-handed singlet, the generation of lepton masses. At zeroth order two neutrinos and one charged lepton are mas…
Neutrinoless double beta decay in an model
V. Pleitez, M. D. Tonasse
We consider a model for the electroweak interactions with gauge symmetry. We show that, it is the conservation of which forbids massive neutrinos an…
Heavy Charged Leptons in an Model
V. Pleitez, M. D. Tonasse
We consider an model for the electroweak interactions which includes extra charged leptons which do not mix with the known leptons. These new leptons couple…
Constraints on singlet right-handed neutrinos coming from the -width
C. O. Escobar, O. L. G. Peres, V. Pleitez +1
We study the constraints on masses and mixing angles imposed by the measured invisible width, in a model in which a singlet right-handed neutrino mixes with all the Standard…
