论文摘要
标准的$λ$冷暗物质宇宙学模型可为当前的宇宙学数据提供出色的拟合度，但是通过最新的数据分析，一些紧张和异常在统计上具有统计学意义。尽管这些异常可能是由于实验中存在系统错误的原因，但它们也可能表明除了标准模型之外需要新物理学。在这封信中，我们着重于具有弱透镜测量和红移调查的Planck数据的张力，有关物质能量密度$ω_m$的价值以及结构增长的幅度或速度（$σ_8，Fσ_8$）。我们列出了一些有趣的模型来解决这种张力，并讨论了尝试与单个模型拟合的全部数据，而不仅仅是一个参数。
The standard $Λ$ Cold Dark Matter cosmological model provides a wonderful fit to current cosmological data, but a few tensions and anomalies became statistically significant with the latest data analyses. While these anomalies could be due to the presence of systematic errors in the experiments, they could also indicate the need for new physics beyond the standard model. In this Letter of Interest we focus on the tension of the Planck data with weak lensing measurements and redshift surveys, about the value of the matter energy density $Ω_m$, and the amplitude or rate of the growth of structure ($σ_8,fσ_8$). We list a few interesting models for solving this tension, and we discuss the importance of trying to fit with a single model a full array of data and not just one parameter at a time.
