论文摘要
$ S $ -Matrix的重力公式不包括Sitter Vacua。特别是，这是有机与字符串理论。 $ s $ -matrix约束由异常的量子断裂时间与重力和/或字符串耦合的反值成比例。因此，De Sitter只能以对重力和封闭串联的$ S $ Matrixes的费用而满足有效真空的条件。在非零引力和弦线耦合下，de Sitter被Colduscular $ 1/N $效果变形，类似于QCD中的Witten-Veneziano机制，带有$ N $颜色。在这张照片中，爱因斯坦重力的$ S $ -MATRIX公式（例如弦乐理论）无效了出色的宇宙学难题。我们讨论了可能在大量粒子物种的理论中特别有趣的观察性特征。即使标准的充气量波动可以忽略不计，物种也可以将原始量子烙印提高到可能可观察到的水平。
$S$-matrix formulation of gravity excludes de Sitter vacua. In particular, this is organic to string theory. The $S$-matrix constraint is enforced by an anomalous quantum break-time proportional to the inverse values of gravitational and/or string couplings. Due to this, de Sitter can satisfy the conditions for a valid vacuum only at the expense of trivializing the graviton and closed-string $S$-matrixes. At non-zero gravitational and string couplings, de Sitter is deformed by corpuscular $1/N$ effects, similarly to Witten-Veneziano mechanism in QCD with $N$ colors. In this picture, an $S$-matrix formulation of Einstein gravity, such as string theory, nullifies an outstanding cosmological puzzle. We discuss possible observational signatures which are especially interesting in theories with large number of particle species. Species can enhance the primordial quantum imprints to potentially observable level even if the standard inflaton fluctuations are negligible.
