论文摘要
在本文中，我们研究了模块化$γ^{\ prime} _5 \ simeq a^{\ prime} _5 $对称对中微子振荡现象学在线性seesaw seesaw框架中的含义。为了实现线性Seesaw机制所决定的光活性中微子的明确定义的质量结构，我们引入了六个重型费米昂领域以及一对重物，以保留超电势的霍明态性质。模块化对称性的显着特征是，它大大降低了Flavon场的使用情况。此外，Yukawa耦合在风味对称组下非琐事地转换，并根据Dedekind ETA函数表示，其$ Q $扩展在计算中具有数值简单性。我们证明该模型框架有效地适合所有中微子振荡数据。在旁边，我们还研究了从最轻的繁重费米斯衰减产生的CP不对称的作用，以通过瘦素发生的现象来解释观察到的Baryon不对称性。
In this paper, we investigate the implication of modular $Γ^{\prime}_5 \simeq A^{\prime}_5$ symmetry on neutrino oscillation phenomenology in the linear seesaw framework. In order to achieve the well defined mass structure for the light active neutrinos as dictated by the linear seesaw mechanism, we introduce six heavy fermion fields along with a pair of weightons to retain the holomorphic nature of the superpotential. The notable feature of modular symmetry is that, it reduces the usage of flavon fields significantly. In addition, the Yukawa couplings transform non-trivially under the flavor symmetry group and expressed in terms of the Dedekind eta functions, the $q$ expansion of which renders numerical simplicity in calculations. We demonstrate that the model framework diligently accommodates all the neutrino oscillation data. Alongside, we also investigate the effect of CP asymmetry generated from the decay of lightest heavy fermions to explain the observed baryon asymmetry through the phenomenon of leptogenesis.
