论文摘要
暗物质（DM）与可见扇区的相互作用通常在简化模型的框架中进行现象学描述，在这些模型的框架中，夸克与新粒子的耦合通常被认为是通用的，或者具有观察基准动机的简单结构。但是，他们应该先验地将其视为免费参数。在这项工作中，我们讨论了基于$ s_4 \ times z_5 $风味对称性的DM耦合结构的一个特殊认识，该味道已被证明可以很好地解释Fermion群众和混合，并将其对观察信号的效果与通用的效果进行比较，并与Yukawa类似于Yukawa类似于Yukawa like couplings，这受到最小化的风味。我们还将评论如何在DM的紫外线完整理论中限制这些结构，以及如何可能将DM可观察物（例如，遗物密度和直接检测）用作潜在风味对称性的吸烟枪。
The interactions of dark matter (DM) with the visible sector are often phenomenologically described in the framework of simplified models where the couplings of quarks to the new particles are generally assumed to be universal or have a simple structure motivated by observational benchmarks. They should, however, a priori be treated as free parameters. In this work we discuss one particular realization of the structure of DM couplings based on an $S_4 \times Z_5$ flavor symmetry, which has been shown to account reasonably well for fermion masses and mixing, and compare their effect on observational signals to universal as well as Yukawa-like couplings, which are motivated by minimal flavor violation. We will also comment on how these structures could be constrained in UV complete theories of DM and how DM observables, such as, e.g., relic density and direct detection, can potentially be used as a smoking gun for the underlying flavor symmetries.
