摘要:

我们认为第一次7级模块不变的味道模型,轻子混合起源于模块对称性和耦合负责轻子质量的模块形式的破坏。后者被分解为有限模群$Γ_7$的不可约多重组,$Γ_7$同构于$PSL(2,Z_{7})$,$PSL(2,Z_{7})$是包含168个元素的有限伽罗瓦域上的二维矩阵的射影特殊线性群,有时写为$PSL_2(7)$或$Σ(168)$。在权重2处,有26个线性独立的模形式,被组织成$Γ_7$的一个三位组、一个七位组和两个八位组。一个完整的列表模块形式的重量高达8提供。假设没有黄酮,最简单的模块不变模型的基础上$Γ_7$的构建,其中中微子获得质量通过温伯格运营商或I型跷跷板机制,和他们的预测相比,实验。

英文摘要:

We consider for the first time level 7 modular invariant flavour models where the lepton mixing originates from the breaking of modular symmetry and couplings responsible for lepton masses are modular forms. The latter are decomposed into irreducible multiplets of the finite modular group $Γ_7$, which is isomorphic to $PSL(2,Z_{7})$, the projective special linear group of two dimensional matrices over the finite Galois field of seven elements, containing 168 elements, sometimes written as $PSL_2(7)$ or $Σ(168)$. At weight 2, there are 26 linearly independent modular forms, organised into a triplet, a septet and two octets of $Γ_7$. A full list of modular forms up to weight 8 are provided. Assuming the absence of flavons, the simplest modular-invariant models based on $Γ_7$ are constructed, in which neutrinos gain masses via either the Weinberg operator or the type-I seesaw mechanism, and their predictions compared to experiment.
