One small step for an inflaton, one giant leap for inflation: A novel non-Gaussian tail and primordial black holes
We report a novel prediction from single-field inflation that even a tiny step in the inflaton potential can change our perception of primordial non-Gaussianities of the curvature perturbation. Our analysis focuses on the tail of probability distribution generated by an upward step transition betwee...
