Light Dark Matter from Self-cooling Dark Sectors
Esau Cervantes, Andrzej Hryczuk, Stefan Lederer
Light thermally produced dark matter is subject to strong bounds stemming from its free-streaming impact on suppressing structure formation. In this paper we show that these limits…

BSFfast: Rapid computation of bound-state effects on annihilation in the early Universe
Tobias Binder, Mathias Garny, Jan Heisig +1
Bound-state formation (BSF) can have a large impact on annihilation of new physics particles with long-range interactions in the early Universe. In particular, the inclusion of exc…

Perturbative Unitarity Violation in Radiative Capture Transitions to Dark Matter Bound States
Martin Beneke, Tobias Binder, Lorenzo de Ros +2
We investigate the formation of bound states of non-relativistic dark matter particles subject to long-range interactions through radiative capture. The initial scattering and fina…
