چکیده
The possibility of adding an SU (2) horizontal symmetry to the 331 model is studied. It is found that simple, anomaly-free fermion assignments can be made which lead to plausible results for fermion masses and mixings. In particular, all particles of the first generation are massless at tree-level, and the CKM matrix acquires a realistic form.

We calculate the exact tree-level scalar mass matrices resulting from symmetry breaking using the most general gauge-invariant scalar potential of the 331 model, both with and without the condition that lepton number is conserved. Physical masses are also obtained in some cases, as well as couplings to standard and exotic gauge bosons.

We suggest that a singlet fermion S exists beyond the standard see-saw structure. It mixes with light neutrinos via interactions with the right-handed neutrino components, so that νe → S conversion solves the solar neutrino problem. Supersymmetry endowed with R-symmetry is shown to give a natural framework for existence, mass scale and mixing (sin 2θes ∼ (0.1− 1.5) · 10) of such a fermion. Mode...

Models of neutrino masses are discussed capable of explaining in a natural way the maximal mixing between ν µ and ν τ observed by the Super-Kamiokande collaboration. For three generations of leptons two classes of such models are found implying: a) ∆m 23 2 ≪ ∆m 12 2 ≈ ∆m 13 2 and a small mixing between ν e and the other two neutrinos, b) ∆m 12 2 ≪ ∆m 13 2 ≈ ∆m 23 2 and a nearly maximal mixing f...

A model is constructed for a chiral abelian gauge-interaction of fermions and a potential of three higgses, so that the potential possesses a discrete symmetry of the vacuum state, which provides the introduction of three generations for the fermions. For the model including charged currents, a matrix of the flavor mixing is described, and a phase giving the violation of CP-invariance is determ...
