标题： The impact of non-perturbative effects in dark matter production and detection

摘要： 暗物质是粒子物理学和宇宙学中最重要的未解之谜之一。 我们研究了非微扰效应对暗物质产生以及对直接探测和间接探测的影响，以深入了解其基本性质。 具体而言，我们重点关注索末菲增强和暗物质束缚态的形成，这两者都可能改变总的暗物质湮灭截面，从而修改早期和晚期宇宙中的暗物质可观测量。 为此，我们进行了两项研究，分别聚焦于不同的暗物质可观测量，这些可观测量很可能会被即将进行的实验探测到。 显示英文摘要

摘要： Dark matter stands out as one of the most important unsolved mysteries in particle physics and cosmology. We investigate the influence of non-perturbative effects on the production of dark matter as well as their impact on direct and indirect detection to attain insight on its fundamental nature. Specifically, we focus on Sommerfeld enhancement and the formation of dark matter bound states both of which can alter the total dark matter annihilation cross section and thus modify dark matter observables in the early and late Universe. To this end, we conducted two studies focusing on different dark matter observables, which are likely to be probed by upcoming experiments.
