Flavored non-minimal left–right symmetric model fermion masses and mixings
Abstract A complete study on the fermion masses and flavor mixing is presented in a non-minimal left–right symmetric model (NMLRMS) where the $$\mathbf{S}_{3}\otimes \mathbf{Z}_{2}\otimes \mathbf{Z}^{e}_{2}$$ S3⊗Z2⊗Z2e flavor symmetry drives the Yukawa couplings. In the quark sector, the mass matric...

| Summary: | Abstract A complete study on the fermion masses and flavor mixing is presented in a non-minimal left–right symmetric model (NMLRMS) where the $$\mathbf{S}_{3}\otimes \mathbf{Z}_{2}\otimes \mathbf{Z}^{e}_{2}$$ S3⊗Z2⊗Z2e flavor symmetry drives the Yukawa couplings. In the quark sector, the mass matrices possess a kind of generalized Fritzsch textures that allow us to fit the CKM mixing matrix in good agreement to the latest experimental data. In the lepton sector, on the other hand, a soft breaking of the $$\mu \leftrightarrow \tau $$ μ↔τ symmetry provides nonzero and nonmaximal reactor and atmospheric angles, respectively. The inverted and degenerate hierarchies are favored in the model where a set of free parameters is found to be consistent with the current neutrino data. |
