A Lower Bound on Dark Matter Mass
Mustafa A. Amin, Mehrdad Mirbabayi
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 nondetection of free-streaming suppression and white-noise enhancement of density perturbations as the observational inputs.
