Two-Loop Corrections in Power Spectrum in Models of Inflation with Primordial Black Hole Formation
We calculated the two-loop corrections in the primordial power spectrum in models of single-field inflation incorporating an intermediate USR phase employed for PBH formation. Among the overall eleven one-particle irreducible Feynman diagrams, we calculated the corrections from the “double scoop” tw...
