$S_4 \times Z_5$味对称框架中的暗物质相互作用

Dark Matter interactions in an $S_4 \times Z_5$ flavor symmetry framework

Giorgio Arcadi, Davide Meloni, Martin B. Krauss

摘要:

暗物质(DM)与可见光区的相互作用通常在简化模型的框架中进行唯象描述,其中夸克与新粒子的耦合通常被假设为是普遍的或具有由观测基准激发的简单结构。然而,它们应该先验地被视为自由参数。在这项工作中,我们讨论了一个特定的实现DM耦合的结构的基础上的$S_4 \times Z_5$味对称性,这已被证明是合理的费米子质量和混合,并比较其对观测信号的影响,以普遍以及汤川耦合,这是出于最小的味违反。我们还将评论这些结构如何在DM的UV完备理论中受到约束,以及DM观测量如何,例如,残留密度和直接检测,可以潜在地用作潜在的味道对称性的吸烟枪。

英文摘要:

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.
