模不变味模型中的对称性和稳定子

Symmetries and stabilisers in modular invariant flavour models

Ivo de Medeiros Varzielas, Miguel Levy, Ye-Ling Zhou

摘要:

模不变性的思想为风味混合提供了一种新的解释。在有限模对称$Γ_N$的上下文中,对于给定的元素$γ\in Γ_N$,我们提出了一种算法,用于寻找稳定剂(特定值的模字段$τ_γ$下保持不变的行动与$γ$)。然后,我们使用该算法找到所有的稳定器为每个元素的有限模群的$N=2$ $5$,即,$Γ_2\simeq S_3$,$Γ_3\simeq A_4$,$Γ_4\simeq S_4$和$Γ_5\simeq A_5$。然后这些稳定剂保留$Γ_N$的特定环状亚组。这是感兴趣的建立模型的费米子混合,其中每个费米子部门保留一个单独的剩余对称性。

英文摘要:

The idea of modular invariance provides a novel explanation of flavour mixing. Within the context of finite modular symmetries $Γ_N$ and for a given element $γ\in Γ_N$, we present an algorithm for finding stabilisers (specific values for moduli fields $τ_γ$ which remain unchanged under the action associated to $γ$). We then employ this algorithm to find all stabilisers for each element of finite modular groups for $N=2$ to $5$, namely, $Γ_2\simeq S_3$, $Γ_3\simeq A_4$, $Γ_4\simeq S_4$ and $Γ_5\simeq A_5$. These stabilisers then leave preserved a specific cyclic subgroup of $Γ_N$. This is of interest to build models of fermionic mixing where each fermionic sector preserves a separate residual symmetry.
