Gravitational production of nearly thermal fermionic Dark Matter
Nathan Herring, Daniel Boyanovsky
We consider the cosmological production of fermionic dark matter during inflation and a post-inflationary radiation dominated era. This fermion \emph{only interacts gravitationally…
Non-adiabatic cosmological production of ultra-light Dark Matter
Nathan Herring, Daniel Boyanovsky, Andrew R. Zentner
We study the non-adiabatic cosmological production of ultra light dark matter (ULDM) under a minimal set of assumptions: a free ultra light real scalar as a spectator field in its…
Cosmological decay of Higgs-like scalars into a fermion channel
Daniel Boyanovsky, Nathan Herring
We study the decay of a Higgs-like scalar Yukawa coupled to massless fermions in post-inflationary cosmology, combining a non-perturbative method with an adiabatic expansion. The r…
Particle decay in post inflationary cosmology
Nathan Herring, Brian Pardo, Daniel Boyanovsky +1
We study scalar particle decay during the radiation and matter dominated epochs of a standard cosmological model. An adiabatic approximation is introduced that is valid for degrees…
