论文摘要
冷星云为发现暗物质提供了一种令人兴奋的新方法。它们的巨大尺寸使它们对最重，最稀有的暗物质模型的相互作用具有独特的敏感。使用气云观察，我们通过浅色暗光子对深色的型暗物质对重型复合暗物质产生限制，直至一千个太阳能。我们发现气体云也对通过固定的接触相互作用横截面与核相互作用的非常大的复合暗物质敏感。我们还研究了接触交互模型，并实施了多室和过度分析，以从CDM，CRESST，DAMA，XQC和XENON1T等实验中获得界限。
Cold interstellar gas clouds provide an exciting new method to discover dark matter. Their immense size makes them uniquely sensitive to interactions from the heaviest, most rarefied dark matter models. Using gas cloud observations, we derive constraints on heavy composite dark matter coupled to the Standard Model through a light dark photon for dark matter up to a thousand solar masses. We find gas clouds are also sensitive to very large composite dark matter that interacts with nuclei through a fixed contact interaction cross section. We also study the contact interaction model and implement multiscatter and overburden analyses to obtain bounds from experiments like CDMS, CRESST, DAMA, XQC, and XENON1T.
