标题： Inflationary Potential as seen from Different Angles: Model Compatibility from Multiple CMB Missions

摘要： 宇宙微波背景（CMB）温度和极化各向异性，如WMAP、普朗克以及最近的阿塔卡马宇宙学望远镜和南极望远镜等独立天文任务所观测到的，已经在准确约束宇宙学理论和模型中发挥了重要作用，确立了宇宙暴胀作为描述早期宇宙物理的最广泛接受的理论。然而，B模式极化未被明确检测到，以及不同CMB实验之间出现的差异，给确定哪种暴胀模型最能解释观测数据带来了挑战。在本工作中，我们进一步探讨了这一困难，并通过分析四种著名的暴胀势能在最新发布的普朗克卫星和阿塔卡马宇宙学望远镜的CMB温度和极化各向异性测量以及透镜数据背景下的案例研究。此外，我们还结合了BICEP/Keck合作项目的B模式极化数据，以及BOSS DR12和eBOSS DR16的重子声学振荡和红移空间畸变测量数据。我们表明，典型的模型如Starobinsky和$\alpha$-吸引子与阿塔卡马宇宙学望远镜的小尺度CMB测量结果不一致，尤其是在结合B模式极化数据时。另一方面，这些势能在较大的角度尺度上与普朗克测量结果完全一致。这种二元性使得很难识别出一个或一组模型，可以基于所有可用的CMB观测结果被普遍认为是首选选择。 显示英文摘要

摘要： The cosmic microwave background (CMB) temperature and polarization anisotropies, as observed by independent astronomical missions such as WMAP, Planck, and most recently the Atacama Cosmology Telescope and the South Pole Telescope have played a vital role in accurately constraining cosmological theories and models, establishing cosmic inflation as the most widely accepted theory for describing the physics of the early Universe. However, the absence of a definitive detection of B-mode polarization and the emerging discrepancies among different CMB experiments present a challenge in determining which inflationary models best explain the observed data. In this work, we further explore this difficulty and conduct a case study by analyzing four well-known inflationary potentials in light of the latest CMB temperature and polarization anisotropy measurements and lensing data released by the Planck satellite and the Atacama Cosmology Telescope. Additionally, we incorporate B-modes polarization data from the BICEP/Keck Collaboration, as well as Baryon Acoustic Oscillations and Redshift Space Distortions measurements from BOSS DR12 and eBOSS DR16. We show that the most typical models such as Starobinsky and $\alpha$-attractors are in disagreement with the Atacama Cosmology Telescope small-scale CMB measurements, particularly when combined with B-modes polarization data. On the other hand, these potentials are in perfect agreement with the Planck measurements at larger angular scales. This dichotomy makes it challenging to identify a single model or a group of models that can be universally considered as the preferred choice based on all available CMB observations.
