Scalar contributions to the S, T, U parameters in a 3-3-1 model
A. Doff, C. A. de S. Pires
Electroweak precision tests, expressed through the oblique parameters , , and , impose stringent constraints on physics beyond the Standard Model. Gauge extensions of the…

Type-II Seesaw Mechanism for Dirac Neutrinos and its Implications on and Lepton Flavor Violation in a 3-3-1 model
VinÃcius Oliveira, Patricio Escalona, Lucia Angel +2
In this study, we implement the type-II seesaw mechanism for Dirac neutrino masses within the framework of a 3-3-1 model. To this end, we introduce a scalar sextet and impose both…

Meson Mixing Bounds on Mass in the Alignment Limit: Establishing the Phenomenological Viability of the 331 Model
Patricio Escalona, João Paulo Pinheiro, A. Doff +1
We perform a systematic study of flavor-changing neutral currents (FCNCs) in the 331 model with right-handed neutrinos (331RHNs), analyzing constraints on the boson mass…
