The simplest curvaton model

journal contribution
posted on 2023-06-07, 14:28 authored by Andrew Liddle, N. Bartolo
We analyze the simplest possible realization of the curvaton scenario, where a nearly scale-invariant spectrum of adiabatic perturbations is generated by conversion of an isocurvature perturbation generated during inflation, rather than the usual inflationary mechanism. We explicitly evaluate all the constraints on the model, under both the assumptions of prompt and delayed reheating, and we outline the viable parameter space.
