论文摘要
标准$λ$ CDM模型的哈勃张力可以通过预聚类的早期暗能量来解决。我们使用最新的二头肌/凯克宇宙微波背景（CMB）B模式极化数据对相应的Hubble-Teension-Nie-teension宇宙学中的张量与尺度比率$ r $ r $介绍了第一个约束。我们发现，将二头肌/凯克与Planck18 CMB和Baryon声学振荡数据相结合，具有较大哈勃常数$ H_0 $的模型将在$ r $上具有更严格的上限，并且分辨率$ h_0 \ sim73 $ km/s/s/s/s/s/s/s/s/s/s/s/s/mpc hubble the上界限$ r <0.028 \ r <0.0028 \ \ 0.028 \ （95 \％\ text {c.l。}）$，$ 25 \％$比$λ$ cdm约束$ r <0.036 $。我们阐明了这种紧缩界限的起源。
The Hubble tension that the standard $Λ$CDM model is suffering from can be resolved with pre-recombination early dark energy. We present the first constraint on the tensor-to-scalar ratio $r$ in corresponding Hubble-tension-free cosmologies using the most recent BICEP/Keck cosmic microwave background (CMB) B-mode polarization data. We find, combining BICEP/Keck with Planck18 CMB and baryon acoustic oscillation data, that the models with larger Hubble constant $H_0$ will have tighter upper bound on $r$, and resolution $H_0\sim73$ km/s/Mpc of the Hubble tension tightens the upper bound to $r<0.028\ (95\%\text{C.L.})$, $25\%$ tighter than the $Λ$CDM constraint $r<0.036$. We clarify the origin of this tightening bound.
