Strong restriction on inflationary vacua from the local gauge invariance III: Infrared regularity of graviton loops
It has been claimed that the super-Hubble modes of the graviton generated during inflation can make loop corrections diverge. Even if we introduce an infrared (IR) cutoff at a comoving scale as an ad hoc but practical method of regularization, we encounter secular growth, which may lead to the break...
