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…

Excited bound states and their role in dark matter production

Tobias Binder, Mathias Garny, Jan Heisig +2

We explore the impact of highly excited bound states on the evolution of number densities of new physics particles, specifically dark matter, in the early Universe. Focusing on dip…

Electroweak resummation of neutralino dark-matter annihilation into high-energy photons

Martin Beneke, Stefan Lederer, Clara Peset

We consider the resummation of large electroweak Sudakov logarithms for the annihilation of neutralino DM with (TeV) mass to high-energy photons in the minimal supersy…

Sommerfeld enhancement of resonant dark matter annihilation

Martin Beneke, Stefan Lederer, Kai Urban

The dark matter annihilation cross section can be amplified by orders of magnitude if the annihilation occurs into a narrow resonance, or if the dark-matter particles experience a…
