Sommerfeld Effect and Bound State Formation for Dark Matter Models with Colored Mediators with SE+BSF4DM

Mathias Becker, Emanuele Copello, Julia Harz +1

In the universal framework of simplified -channel dark matter models, the calculation of the relic abundance can be dominated by mediator annihilation when the dark matter and m…

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…
