物种标度与原初引力波

Species Scale and Primordial Gravitational Waves

Marco Scalisi

AI总结:

本文证明在暴胀宇宙学中,原初引力波的探测可通过张标比 r 为物种标度的衰减率设定数量级为 1 的上限,并与当前及下一代实验目标相符。

摘要:

物种标度是任何与引力弱耦合的有效场论的一个依赖于场的紫外截断。在本文中,我们证明,在暴胀宇宙学的背景下,对原初引力波的探测将为物种标度的衰减率 $|Λ'_s/Λ_s|$ 设定一个上限。具体而言,我们通过原初扰动功率谱的张标比 $r$ 来推导这一上限。鉴于当前和下一代实验的目标,我们证明任何成功的探测都将意味着这一上限的数量级为 1,这与文献中最近的讨论一致。

英文摘要:

The species scale is a field-dependent UV cut-off for any effective field theory weakly coupled to gravity. In this letter we show that, in the context of inflationary cosmology, a detection of primordial gravitational waves will set an upper bound on the decay rate $|Λ'_s/Λ_s|$ of the species scale. Specifically, we derive this in terms of the tensor-to-scalar ratio $r$ of power spectra of primordial perturbations. Given the targets of current and next generation experiments, we show that any successful detection would signify that this upper limit is of the order of unity, which is consistent with recent discussions in the literature.
