Flavored non-minimal left–right symmetric model fermion masses and mixings

A complete study on the fermion masses and flavor mixing is presented in a non-minimal left–right symmetric model (NMLRMS) where the S3⊗Z2⊗Z2e\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\mathbf{S}_{3}\otimes \mathbf{Z}_{2}\otimes \mathbf{Z}^{e}_{2}$$\end{document} 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 μ↔τ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\mu \leftrightarrow \tau $$\end{document} 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.
