Natural units, numbers and numerical clusters
F. Pisano, N. O. Reis
Defined by Lord Kelvin as the science of measurement it is described a fundamental fact of physics. The so called `natural' units represent the unique system of units conveniently…
Cosmological constant and spontaneous gauge symmetry breaking: the particle physics and cosmology interface charade
F. Pisano, N. O. Reis
We describe one of the remarkable problems of theoretical physics persevering up to the beginning of the millennium. All gaugetheories with spontaneous gauge symmetry breaking from…
On the color simple group from chiral electroweak gauge groups
A. Doff, F. Pisano
Following the pioneering Okubo scrutiny of gauge simple groups for the quantum chromodynamics we show the constraints coming from the wondrous predictive leptoquark-bilepton flavor…
Quantization of eletric charge, the neutrino and generation nonuniversality
A. Doff, F. Pisano
text of abstract It is showed that the eletric charge quantization is unconnected to Majorana neutrino in the non-universal generations leptoquark-bilepton flavordynamics which inc…
Minimal extended flavor groups, matter fields chiral representations, and the flavor question
A. Doff, F. Pisano
We show the specific unusual features on chiral gauge anomalies cancellation in the minimal, necessarily 3-3-1, and the largest 3-4-1 weak isospin chiral gauge semisimple group lep…
Reply to ``Comment on `Majoron emitting neutrinoless double beta decay in the electroweak chiral gauge extensions' ''
S. Shelly Sharma, F. Pisano
We demonstrate that in the process of deducing the constraint on the electroweak mixing angle in our paper, we have indeed been working with three mass scales while impleme…
Charge quantization in the largest leptoquark-bilepton chiral electroweak scheme
A. Doff, F. Pisano
The uniqueness of the hypercharge assignments in the three fermion families leptoquark-bilepton model is established. Although the gauge grou…
Charged right-handed currents in the leptoquark-bilepton flavordynamics chiral models
A. A. Machado, F. Pisano
Flavordynamics chiral models of leptoquark fermions and bilepton gauge bosons with masses up to about 1 TeV, although coincident at low energy with the standard model, address the…
Constraints on free parameters of the simplest bilepton gauge model from the neutral kaon system mass difference
F. Pisano, J. A. Silva-Sobrinho, M. D. Tonasse
We consider the contributions of the exotic quarks and gauge bosons to the mass difference between the short- and the long-lived neutral kaon states in $SU(3)_C \times SU(3)_L \tim…
Majoron emitting neutrinoless double beta decay in the electroweak chiral gauge extensions
F. Pisano, S. Shelly Sharma
Fundamental mechanisms for Majoron emitting neutrinoless double beta decay in SU(3)_C x G_W x U(1) models, for electroweak flavor chiral extensions, G_W = SU(3)_L and SU(4)_L are p…
A vanishing cosmological constant in elementary particle theory
F. Pisano, M. D. Tonasse
The quest of a vanishing cosmological constant is considered in the simplest anomaly-free chiral gauge extension of the electroweak standard model where the new physics is limited…
A Simple Solution for the Flavor Question
Felice Pisano
We consider a simple way for solving the flavor question by embedding the three-familiy Standard Model in a semisimple gauge group extending minimally the weak isospin factor. Quan…
Neutrinos and Electromagnetic Gauge Invariance
F. Pisano, J. A. Silva-Sobrinho, M. D. Tonasse
It is discussed a recently proposed connection among U(1) electromagnetic gauge invariance and the nature of the neutrino mass terms in the framework of $\mbox {SU(3)}_C…
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…
Does mass difference constraints or \\ claims new physics beyond the Standard Model?
F. Pisano, V. Pleitez
The ratio within the standard model with 3 generations is calculated as a function of the CP nonconserving phase and the quark masses assuming the cur…
Neutral Currents and GIM Mechanism in SU(3)_L X U(1)_N Models for Electroweak Interactions
J. C. Montero, F. Pisano, V. Pleitez
We study the Glashow-Iliopoulos-Maiani mechanism for flavor-changing-neutral-currents suppression in both, the gauge and Higgs sectors, for models with gaug…
Leptons masses in an Gauge Model
R. Foot, O. F. Hernandez, F. Pisano +1
The model of Pisano and Pleitez extends the Standard Model in a particularly nice way, so that for example the anomalies cancel only when the…
Model for Electroweak Interactions
F. Pisano, V. Pleitez
We consider a gauge model based on symmetry in which the lepton number is violated explicitly by charged scalar and gauge bosons, including a vector field with…
