Leptoquark-induced radiative masses for active and sterile neutrinos within the framework of the 3-3-1 model

On the Higgs spectra of the 3-3-1 model with the sextet of scalars engendering the type II seesaw mechanism
Joao Paulo Pinheiro, C. A. de S. Pires
In the 3-3-1 model with right-handed neutrinos, three triplets of scalars engender the correct sequence of symmetry breaking, $SU(3)_C \times SU(3)_L \times U(1)_X \rightarrow SU(3…
Bounds on quark mixing, and mixing angle from flavor changing neutral processes in a 3-3-1 model
Vinícius Oliveira, C. A. de S. Pires
Meson and anti-meson mixing processes constitute an important source of constraints on models that give tree level contributions to flavor violating neutral processes. In electrowe…
Flavor Changing Neutral Current processes and family discrimination in 3-3-1 models
Vinícius Oliveira, C. A. de S. Pires
In 3-3-1 models anomaly cancellation requires that one of the three families of quarks transforms as triplet by with the other two transforming necessarily…
Pandax-4T limits on mass in 3-3-1LHN model
Vinícius Oliveira, C. A. de S. Pires
The framework of the so-called 3-3-1LHN model may accommodate two different, but viable, scenarios of dark matter: one involving a heavy Dirac neutrino , , or another having a…
Confronting the inverse seesaw mechanism with the recent muon g-2 result
João Paulo Pinheiro, C. A. de S. Pires, Farinaldo S. Queiroz +1
Since the heavy neutrinos of the inverse seesaw mechanism mix largely with the standard ones, the charged currents formed with them and the muons have the potential of generating r…
