Dark matter freeze-in from non-equilibrium QFT: towards a consistent treatment of thermal effects
Mathias Becker, Emanuele Copello, Julia Harz +1
We study thermal corrections to a model of real scalar dark matter (DM) interacting feebly with a SM fermion and a gauge-charged vector-like fermion mediator. We employ the Closed-…

Confronting Dark Matter Freeze-In during Reheating with Constraints from Inflation
Mathias Becker, Emanuele Copello, Julia Harz +2
We investigate the production of particle Dark Matter (DM) in a minimal freeze-in model considering a non-instantaneous reheating phase after inflation. We demonstrate that for low…
