论文摘要
我们研究了在模量空间的固定点上实现的残留风味对称性的对称破坏。在超对称模块化不变理论中，需要远离固定点的少量偏离，以实现费米昂的质量层次结构和相当大的CP破坏效果。我们研究了一个人是否可以在类型IIB字符串理论的背景下在固定点附近动态固定模量值。发现弦乐景观更喜欢$ |Δτ| \ simeq 10^{ - 5} $用于复杂结构模量与所有固定点的偏差和CP破坏真空的差异。为了说明固定点周围模量值分布的现象学意义，我们在混凝土$ A_4 $模块化风味模型上分析了Lepton部门。
We study a symmetry breaking of residual flavor symmetries realized at fixed points of the moduli space. In the supersymmetric modular invariant theories, a small departure of the modulus from fixed points is required to realize fermion mass hierarchies and sizable CP-breaking effects. We investigate whether one can dynamically fix the moduli values in the vicinity of the fixed points in the context of Type IIB string theory. It is found that the string landscape prefers $|δτ| \simeq 10^{-5}$ for the deviation of the complex structure modulus from all fixed points and the CP-breaking vacuum is statistically favored. To illustrate phenomenological implications of distributions of moduli values around fixed points, we analyze the lepton sector on a concrete $A_4$ modular flavor model.
