论文摘要
当前的宇宙学探针提供了对标准的$λ$冷暗物质宇宙学模型的绝妙确认，该模型已以前所未有的精度约束。但是，随着实验敏感性的提高，出现了不同独立宇宙学数据集之间的一些统计学意义。尽管这些紧张局势可能处于系统错误的结果，但经过数年准确分析后的持久性强烈暗示了标准宇宙学场景中的裂缝和对新物理学的需求。在这封信中，我们将重点介绍hubble常数$ H_0 $与SH0ES协作测量的Planck估算之间的$4.4σ$张力。在展示了使用不同的方法和几何校准从不同团队进行的$ H_0 $评估之后，我们将列出一些有趣的新物理模型，这些模型可以解决这一张力，并讨论未来十年实验如何至关重要。
The current cosmological probes have provided a fantastic confirmation of the standard $Λ$ Cold Dark Matter cosmological model, that has been constrained with unprecedented accuracy. However, with the increase of the experimental sensitivity a few statistically significant tensions between different independent cosmological datasets emerged. While these tensions can be in portion the result of systematic errors, the persistence after several years of accurate analysis strongly hints at cracks in the standard cosmological scenario and the need for new physics. In this Letter of Interest we will focus on the $4.4σ$ tension between the Planck estimate of the Hubble constant $H_0$ and the SH0ES collaboration measurements. After showing the $H_0$ evaluations made from different teams using different methods and geometric calibrations, we will list a few interesting new physics models that could solve this tension and discuss how the next decade experiments will be crucial.
