Dark QED from inflation

Abstract One contribution to any dark sector’s abundance comes from its gravitational production during inflation. If the dark sector is weakly coupled to the inflaton and the Standard Model, this can be its only production mechanism. For non-interacting dark sectors, such as a free massive fermion...

Dark QED from inflation
description Abstract One contribution to any dark sector’s abundance comes from its gravitational production during inflation.
