Description
How small-scale enhanced scalar fluctuations influence large scales, for instance, the one probed by the CMB, has recently been the object of an intense debate. In this context, I will discuss how one-loop diagrams from small-scale modes may -only apparently- lead to scale invariant corrections at large scales.
I will then discuss ways to have resonant IR cascades, namely cases where loop corrections can be significant in the -near- infrared.
