Title: PBHs from fully non-Gaussian Curvature Perturbations
Abstract: In this talk, we discuss the PBH abundance generated by a strongly non-Gaussian spectator component in the curvature perturbation. As a concrete setup, we study the mixed inflaton-curvaton scenario. We assume a vanishing mean for the curvaton such that the curvature perturbation has no leading Gaussian part. We also require that the curvature perturbation generated by the curvaton has a sufficiently red-tilted spectrum making it negligible on large scales. We set up the formalism for the quadratic potential which generates a Gaussian distributed curvaton field with a power law spectrum. We will also investigate phenomenological setups where the curvaton is Gaussian but the spectrum differs from the power law form and show the phenomenological implications of our result.
