A lower bound on dark matter mass
Abstract
We argue that there is a lower bound of order 10-19 eV on dark matter mass if it is produced after inflation via a process with finite correlation length. We rely on non-detection of free-streaming suppression and white-noise enhancement of density perturbations as the observational inputs.
