Fractionary Charged Particles Confronting Lepton Flavor Violation and the Muon's Anomalous Magnetic Moment
Elmer Ramirez Barreto, Alex G. Dias
In light of the recent result published by the Fermilab Muon experiment, we investigate a simple model that includes particles of fractional electric charges: a colour-sing…
Heavy long-lived fractionally charged leptons in novel model
Elmer Ramirez Barreto, David Romero Abad
It was explored a new electroweak extension of the Standard Model, where new particles arise with peculiar signatures as heavy fractionally charged lep…
Fixing the number of non-sequential generations within the gauge group
Elmer Ramirez Barreto, David Romero Abad
In this work we explore the possibility to fix the number of new non-sequential chiral-type generations of fermions that could be added to the standard model by combining the condi…
Hierarchical Fermions and Detectable from Effective Two-Higgs-Triplet 3-3-1 Model
E. R. Barreto, A. G. Dias, J. Leite +3
We develop a model where the number of fermion generations is fixed by cancellation of gauge anomalies, being a type of 3-3…
Is There a Hidden Principle in the Higgs Boson Decay to Photons?
Alexandre Alves, E. Ramirez Barreto, A. G. Dias
It is remarkable that the measured Higgs boson mass is so close to the value which maximizes the Higgs decay rate to photons as predicted by the Standard Model. In this work we exp…
A Model with Chiral Quarks of Electric Charges -4/3 and 5/3
Alexandre Alves, E. Ramirez Barreto, D. A. Camargo +1
We present a new model based on the SU(3)xSU(2)xU(1) symmetry, in which there is a new consistent set of chiral fermion fields that renders the model free from anomalies. The new f…
