论文摘要
SH0ES协作中哈勃常数的直接延迟测量与基于Planck合作的$λ$ CDM模型的早期测量之间的分歧，至少在原则上可以通过早期宇宙中的新物理学来解释。最近，大规模结构的有效场理论应用于SDSS/BOSS数据的全部功能谱的全部形状，这揭示了一种新的，相当强大的方法，可测量来自大型结构调查的哈勃常数和其他宇宙学参数。鉴于此，我们分析了早期宇宙物理学的两个模型，早期的深色能量和摇滚，这些模型旨在显着改善哈勃张力。在包括从全部形状到普朗克，包和超新星测量的信息后，我们发现这些模型引入的宇宙学参数中的变性被数据弄坏了，因此这两个模型不会显着改善张力。
The disagreement between direct late-time measurements of the Hubble constant from the SH0ES collaboration, and early-universe measurements based on the $Λ$CDM model from the Planck collaboration might, at least in principle, be explained by new physics in the early universe. Recently, the application of the Effective Field Theory of Large-Scale Structure to the full shape of the power spectrum of the SDSS/BOSS data has revealed a new, rather powerful, way to measure the Hubble constant and the other cosmological parameters from Large-Scale Structure surveys. In light of this, we analyze two models for early universe physics, Early Dark Energy and Rock 'n' Roll, that were designed to significantly ameliorate the Hubble tension. Upon including the information from the full shape to the Planck, BAO, and Supernovae measurements, we find that the degeneracies in the cosmological parameters that were introduced by these models are well broken by the data, so that these two models do not significantly ameliorate the tension.
