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, Vinícius 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…
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…
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.…
Introducing scalar leptoquarks into a 3-3-1 model to solve the puzzle
A. Doff, C. A. de S. Pires
In this work we introduce scalar leptoquarks into the 3-3-1 model with right-handed neutrinos with the aim of solving the puzzle. We show that besides the model supports…
Composite scalar bosons masses: Effective potential versus Bethe-Salpeter approach
A. Doff
Ten years ago the GeV Higgs resonance was discovered at the LHC[1,2], if this boson is a fundamental particle or a particle composed of new strongly interacting particles is…
Composite scalar boson mass dependence on the constituent mass anomalous dimension
A. Doff, A. A. Natale
We perform a Bethe-Salpeter equation (BSE) evaluation of composite scalar boson masses in order to verify how these masses can be smaller than the composition scale. The calculatio…
How confinement may affect technicolor?
A. Doff, F. A. Machado, A. A. Natale
Confinement has been introduced into the quark gap equation, as proposed by Cornwall, as a possible solution to the problem of chiral symmetry breaking in QCD with dynamically mass…
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…
