三重极大混合的群论基础

Group Theoretic Bases for Tribimaximal Mixing

Paul D. Carr, Paul H. Frampton

摘要:

目前的数据中微子质量和混合有利于高度对称的tribimmaximal中微子混合矩阵,这表明一个潜在的味道对称性。对$g \leq 31$阶非交换有限群的系统研究表明,三重极大混合不仅可以从著名的味对称$T \equiv A_4$(四面体群)导出,而且可以利用另一种味对称X(24)$\equiv SL_2(F_3) \equiv Q_4 \tilde{\times} Z_3$导出. X(24)不包含四面体群作为子群,并且作为味道对称性具有优于它的优势,它不仅可以同样地保证中微子的双三最大混合,而且还提供了理解夸克质量等级的第一步。

英文摘要:

Present data on neutrino masses and mixing favor the highly symmetric tribimaximal neutrino mixing matrix which suggests an underlying flavor symmetry. A systematic study of non-abelian finite groups of order $g \leq 31$ reveals that tribimaximal mixing can be derived not only from the well known flavor symmetry $T \equiv A_4$, the tetrahedral group, but also by using the alternative flavor symmetry X(24) $\equiv SL_2(F_3) \equiv Q_4 \tilde{\times} Z_3$. X(24) does not contain the tetrahedral group as a subgroup, and has the advantage over it as a flavor symmetry that it can not only underwrite bitrimaximal mixing for neutrinos, equally as well, but also provide a first step to understanding the quark mass hierarchy.
