Scale-invariant 3-3-1-1 model with symmetry
Alex G. Dias, Julio Leite, B. L. Sánchez-Vega
Motivated by a possible interplay between the mechanism of dynamical symmetry breaking and the seesaw mechanism for generating fermion masses, we present a scale-invariant model th…
Axion-Neutrino Interplay in a Gauged Two-Higgs-Doublet Model
Alex G. Dias, Julio Leite, Diego S. V. Gonçalves
We propose a gauged two-Higgs-doublet model (2HDM) featuring an anomalous Peccei-Quinn symmetry, . Dangerous tree-level flavour-changing neutral currents, common in 2HDM…
Natural quark mixing and inverse seesaw in a left-right model with an axion
Alex G. Dias, Julio Leite
We consider a minimal left-right model with a Peccei-Quinn symmetry, where generalised charge conjugation plays the role of the left-right symmetry. We show how the spontaneous bre…
Fermion Mass Hierarchy and Double Seesaw Mechanism in a 3-3-1 Model with an Axion
A. G. Dias, J. Leite, D. D. Lopes +1
We present a model based on the gauge symmetry that relates the mass hierarchy of the fermions with the solution to the strong CP problem thr…
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…
Effective fermion kinematics from a modified quantum gravity
J. Alexandre, J. Leite
We consider a classical fermion and a classical scalar, propagating on two different kinds of 4-dimensional diffeomorphism breaking gravity backgrounds, and we derive the one-loop…
Quasi-relativistic fermions and dynamical flavour oscillations
Jean Alexandre, Julio Leite, Nick E. Mavromatos
We introduce new Lorentz-symmetry violating kinematics for a four-fermion interaction model, where dynamical mass generation is allowed, irrespectively of the strength of the coupl…
Lorentz-Violating Regulator Gauge Fields as the Origin of Dynamical Flavour Oscillations
Jean Alexandre, Julio Leite, Nick E. Mavromatos
We show how a mass mixing matrix can be generated dynamically, for two massless fermion flavours coupled to a Lorentz invariance violating (LIV) gauge field. The LIV features play…
