标题： A Vacuum Phase Transition Solves $H_0$ Tension

摘要： 将普朗克宇宙微波背景数据和更直接的哈勃常数测量数据视为不受系统偏差影响，根据$\Lambda$冷暗物质宇宙学模型解释的哈勃常数$H_0$值存在$\sim 3.3 \sigma$的矛盾。 我们表明，由量子引力效应物理驱动的帕克真空形态变化模型，其参数数量与$\Lambda$冷暗物质模型相同，可以消除$H_0$的矛盾，并能对数据提供更好的拟合（高达$\Delta\chi^2=-7.5$）。 它还缓解了与弱透镜数据和高红移利曼阿尔法森林数据之间的矛盾。 我们分别考虑了引力透镜幅度的尺度依赖性变化，例如由修改引力、中微子质量或冷暗能量所提供的，这是基于低和高CMB多极矩的宇宙学参数估计略有不同的原因。 我们发现没有这样的尺度依赖性是被偏好的。 显示英文摘要

摘要： Taking the Planck cosmic microwave background data and the more direct Hubble constant measurement data as unaffected by systematic offsets, the values of the Hubble constant $H_0$ interpreted within the $\Lambda$CDM cosmological constant and cold dark matter cosmological model are in $\sim 3.3 \sigma$ tension. We show that the Parker vacuum metamorphosis model, physically motivated by quantum gravitational effects and with the same number of parameters as $\Lambda$CDM, can remove the $H_0$ tension, and can give an improved fit to data (up to $\Delta\chi^2=-7.5$). It also ameliorates tensions with weak lensing data and the high redshift Lyman alpha forest data. We separately consider a scale dependent scaling of the gravitational lensing amplitude, such as provided by modified gravity, neutrino mass, or cold dark energy, motivated by the somewhat different cosmological parameter estimates for low and high CMB multipoles. We find that no such scale dependence is preferred.
