Quantum loop effects to the power spectrum of primordial perturbations during ultra slow-roll inflation

We examine the quantum loop effects on the single-field inflationary models in a spatially flat Friedmann-Robertson-Walker cosmological space-time with a general self-interacting scalar field potential, which is modeled in terms of the Hubble flow parameters in the effective field theory approach. I...
