6级模对称性与有限模群的一条新途径

Modular symmetry at level 6 and a new route towards finite modular groups

Cai-Chang Li, Xiang-Gan Liu, Gui-Jun Ding

摘要:

本文提出由两个主同余子群的商构造有限模群$Γ(N')/Γ(N")$,并将模群$SL(2,\mathbb{Z})$推广到一个主同余子群$Γ(N')$ .当$N'=1$ .我们对与$N'=1$和$N"=6$相对应的$Γ'_6$模对称性进行了全面的研究,讨论了具有$Γ'_6$模对称性的轻子质量和混合的五种模型,并对几种典型模型进行了数值研究。考虑了$N'=2$和$N"=6$的情况,有限模群为$Γ(2)/Γ(6)\cong T'$,并构造了一个基准模型.

英文摘要:

We propose to construct the finite modular groups from the quotient of two principal congruence subgroups as $Γ(N')/Γ(N")$, and the modular group $SL(2,\mathbb{Z})$ is extended to a principal congruence subgroup $Γ(N')$. The original modular invariant theory is reproduced when $N'=1$. We perform a comprehensive study of $Γ'_6$ modular symmetry corresponding to $N'=1$ and $N"=6$, five types of models for lepton masses and mixing with $Γ'_6$ modular symmetry are discussed and some example models are studied numerically. The case of $N'=2$ and $N"=6$ is considered, the finite modular group is $Γ(2)/Γ(6)\cong T'$, and a benchmark model is constructed.
