摘要: We provide strong evidence for universality of the inflationary field range: given an accurate measurement (n(s), r), one can infer Delta phi in a model-independent way sub-Planckian regime range classes models. Both tensor-to-scalar ratio as well spectral tilt are essential range. Given Planck constraints on ns, Lyth bound is strengthened by two orders magnitude: whereas original gives r less than or similar to 2 x 10(-3), we find that n(s) = 0.96 brings this down 10(-5).
