Primordial Black Holes from Effective Field Theory of Stochastic Single Field Inflation at NNNLO
Sayantan Choudhury, Ahaskar Karde, Pankaj Padiyar +1
We present a study of the Effective Field Theory (EFT) generalization of stochastic inflation in a model-independent single-field framework and its impact on primordial black hole…
