论文摘要

我们证明,如果我们假设,当我们假设在最初的缓慢滚动时期,今天在CMB实验中探测到哈勃半径时,则可能会放松通货膨胀能量尺度和张量与量表比的严格上限,这可能会有些放松。然而,构建发生这种情况的实际模型似乎是不自然的。

We demonstrate that the strict upper bounds on the energy scale of inflation and on the tensor-to-scalar ratio can be somewhat relaxed if we assume that - after an initial period of slow rolling when scales probed today in CMB experiments exit the Hubble radius - the equation of state of the background changes to correspond to an almost marginally accelerating universe. Constructing an actual model in which this happens appears, however, to be unnatural.
