我们讨论了最新的BICEP/Keck数据发布的暴胀模型的影响,特别强调宇宙吸引子,可以描述所有目前可用的通货膨胀相关的观测数据。这些模型与张量与标量比r的任何值都兼容,一直到r = 0。这一类的一些弦论模型预言10-3 ≤ r ≤ 10-2。这一范围的上半部分可以通过正在进行的BICEP/Keck观测来探索。
We discuss implications of the latest BICEP/Keck data release for inflationary models, with special emphasis on the cosmological attractors which can describe all presently available inflation-related observational data. These models are compatible with any value of the tensor to scalar ratio r, all the way down to r = 0. Some of the string theory motivated models of this class predict 10-3 ≤ r ≤ 10-2. The upper part of this range can be explored by the ongoing BICEP/Keck observations.
