Scalar contributions from minimal model to oblique parameters
A. Doff
Electroweak precision observables, encoded in the oblique parameters , , and , impose stringent constraints on extensions of the Standard Model. In this work, we analyze t…
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…
Three decades of FCNC studies in 3-3-1 model with right-handed neutrinos: from -dominance to the alignment limit
Patricio Escalona, João Paulo Pinheiro, VinÃcius Oliveira +2
Flavor-changing neutral current (FCNC) processes play a prominent role in the search for physics beyond the Standard Model (SM) due to their sensitivity to new physics at the TeV s…
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…
Exploring solutions to the muon g-2 anomaly in a 3-3-1 model under flavor constraints
A. Doff, Joao Paulo Pinheiro, C. A. de S. Pires
The magnetic moment of the muon can receive significant two-loop contributions from a light pseudoscalar. Notably, the spectrum of scalars of 3-3-1 models include one pseudoscalar.…
Leptoquark-induced radiative masses for active and sterile neutrinos within the framework of the 3-3-1 model
A. Doff, João Paulo Pinheiro, C. A. de S. Pires
In this work, we introduce the minimal set of leptoquarks into the 3-3-1 model with right-handed neutrinos, capable of generating radiative masses for active neutrinos. As a main c…
