Abstract

A flavor model based on \(A_{4}\) modular group is proposed. We consider the inverse seesaw mechanism to produce the light neutrino masses. Both neutrino and charged lepton masses are obtained in terms of Yukawa coupling ratios and the module \(\tau\) of the \(A_{4}\) modular form. The calculated lepton parameters (masses and mixings) are in good agreement with the recent neutrino data. The present mixing pattern can be realized as a consequence of deviation from the bimaximal symmetry.

轻子质量和混合的模块化$$ {A} _ {{4}} $$不变性模型

摘要

提出了基于\（A_ {4} \）模块化组的风味模型。我们考虑逆向跷跷板机制产生轻中微子质量。中微子质量和带电荷的轻子质量均根据汤河耦合比和模数（A_ {4} \）的模数\（\ tau \）获得。计算出的轻子参数（质量和混合）与最近的中微子数据非常吻合。由于偏离双最大对称性，可以实现当前的混合模式。
