# Gravitational production of nearly thermal fermionic dark matter

@article{Herring2020GravitationalPO, title={Gravitational production of nearly thermal fermionic dark matter}, author={Nathan Herring and Daniel Boyanovsky}, journal={Physical Review D}, year={2020}, volume={101}, pages={123522} }

We consider the cosmological production of fermionic dark matter during inflation and a post-inflationary radiation dominated era. This fermion \emph{only interacts gravitationally}, has a mass $m$ much smaller than the Hubble scale during inflation (but is otherwise arbitrary) and is in its Bunch-Davies vacuum state during inflation. We focus on superhorizon modes at the end of inflation, and assume instantaneous reheating. We obtain the full energy momentum tensor discussing its…
