用对撞机和宇宙学使顶部暗物质陷入困境:QCD修正的重要性

Cornering top-philic dark matter with colliders and cosmology: the importance of QCD corrections

Benjamin Fuks

摘要:

约束暗物质模型需要对来自对撞机物理学、宇宙学和天体物理学的大量观测量进行精确的预测。考虑了两类顶夸克耦合的暗物质模型,研究了暗物质遗迹密度、直接探测和间接探测以及对撞机搜索在探索模型参数空间中的互补性.此外,我们调查如何高阶校正影响的结果。

英文摘要:

Constraining dark matter models necessitates accurate predictions for large set of observables originating from collider physics, cosmology and astrophysics. We consider two classes of top-philic dark matter models where the dark sector is coupled to the Standard Model via the top quark and study the complementarity of dark matter relic density, direct and indirect detection and collider searches in exploring the model parameter space. We moreover investigate how higher-order corrections affect the results.
