Non-Anomalous Flavor Symmetries and SU(6) × SU(2)ᵣ Model

الأصل · EN

We introduce the flavor symmetry Zₘ × Zₙ × D₄ into the SU(6) × SU(2)ᵣ string-inspired model. The cyclic group Zₘ and the dihedral group D₄ are R symmetries, while Zₙ is a non-R symmetry. By imposing the anomaly-free conditions on the model, we obtain a viable solution under many phenomenological constraints coming from the particle spectra. For neutrino sector, we find a LMA-MSW solution but not SMA-MSW ones. The solution includes phenomenologically acceptable results concerning fermion masses and mixings and also concerning hierarchical energy scales including the GUT scale, the μ scale and the Majorana mass scale of R-handed neutrinos.
