扭曲Friedberg-Lee对称的三双峰混合

Tri-Bimaximal Mixing from Twisted Friedberg-Lee Symmetry

Takeshi Araki, Ryo Takahashi

摘要:

本文研究了Friedberg-Lee(FL)对称性及其推广到$μ- τ$对称性的情况,称之为扭曲FL对称性,并基于扭曲FL对称性,提出了两种可能的中微子质量谱和三双峰混合方案:第一种方案,第二种是基于$S_3$置换族对称性的半一致平移,介绍了两种不同的双绞线FL对称方案,并给出了各种方案中的可行模型。

英文摘要:

We investigate the Friedberg-Lee (FL) symmetry and its promotion to include the $μ- τ$ symmetry, and call that the twisted FL symmetry.Based on the twisted FL symmetry, two possible schemes are presented toward the realistic neutrino mass spectrum and the tri-bimaximal mixing.In the first scheme, we suggest the semi-uniform translation of the FL symmetry.The second one is based on the $S_3$ permutation family symmetry.The breaking terms, which are twisted FL symmetric, are introduced.Some viable models in each scheme are also presented.
