论文摘要
压缩杂种弦理论的框架提供了粒子物理标准模型（SM）的一致紫外线（UV）。在这种方法中，SM之外的风味对称性的存在是必须的，并且风味对称性可以源自自上而下。这样的推导揭示了传统离散风味对称性的统一起源，离散的模块化风味对称性，超对称性的离散r对称性以及CP对称性 - 完全称为折衷的风味对称性。我将展示这样自上而下的衍生折衷风味对称性的具体示例，讨论破坏折衷风味对称性的不同来源，以及自下而上风味模型构建的可能的教训。
The framework of compactified heterotic string theory offers consistent ultraviolet (UV) completions of the Standard Model (SM) of particle physics. In this approach, the existence of flavor symmetries beyond the SM is imperative and the flavor symmetries can be derived from the top-down. Such a derivation uncovers a unified origin of traditional discrete flavor symmetries, discrete modular flavor symmetries, discrete R symmetries of supersymmetry, as well as CP symmetry - altogether called the eclectic flavor symmetry. I will show a specific example of such a top-down derived eclectic flavor symmetry, discuss the different sources of breaking of the eclectic flavor symmetry, as well as the possible lessons for bottom-up flavor model building.
