论文摘要
目前的工作灵感来自线性Seesaw框架中$ A_4 $模块化对称性的应用,该框架限制了多个Flavon字段的使用。线性Seesaw用六个重型$ SU(2)_l $ Singlet费米昂超级场和一个在超对称框架中的重物量实现。在$ A_4 $模块化对称性下,Yukawa耦合的非平凡转变有助于探索具有质量基质特定风味结构的中微子现象学。我们讨论了中微子混合的现象,并表明在此框架中获得的混合角度和违反CP违反阶段与观察到的当前振荡数据的$3σ$范围兼容。此外,我们还研究了最轻的繁重费米昂超级场衰减中的非零CP不对称性,以通过诱导生成(包括风味效应)来解释Baryogenogeny的首选现象。
The present work is inspired by the application of $A_4$ modular symmetry in the linear seesaw framework, which restricts the use of multiple flavon fields. Linear seesaw is realized with six heavy $SU(2)_L$ singlet fermion superfields and a weighton in a supersymmetric framework. The non-trivial transformation of Yukawa couplings under the $A_4$ modular symmetry helps to explore the neutrino phenomenology with a specific flavor structure of the mass matrix. We discuss the phenomena of neutrino mixing and show that the obtained mixing angles and CP violating phase in this framework are compatible with the observed $3σ$ range of the current oscillation data. In addition, we also investigate the non-zero CP asymmetry from the decay of lightest heavy fermion superfield to explain the preferred phenomena of baryogenesis through leptogenesis including flavor effects.
