Fermion Masses and Mixing in 331 Models with Horizontal Symmetry
arXiv:hep-ph/9807201 · doi:10.1142/S0217732398002187
Abstract
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.
