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…
Exploring non-equilibrium effects in sequential freeze-in
Shiuli Chatterjee, Andrzej Hryczuk
Freeze-in of multi-component dark sectors is governed not only by the interaction with the thermal plasma, but also by their internal dynamics. Full thermalisation within the dark…
Freezing-in Cannibals with Low-reheating Temperature
Nicolás Bernal, Esau Cervantes, Kuldeep Deka +1
The freeze-in mechanism provides a compelling framework for dark matter (DM) production, particularly suited to scenarios involving feeble interactions with the Standard Model (SM)…
Conversions in two-component dark sectors: a phase space level analysis
Shiuli Chatterjee, Andrzej Hryczuk
Conversions between the states in the dark sector affect not only their number densities but also their momentum distributions. In this work we study a phenomenologically motivated…
Freezing-in Cannibal Dark Sectors
Esau Cervantes, Andrzej Hryczuk
Self-Interacting Dark Matter models can successfully explain dark matter (DM) production through interactions confined within the dark sector. However, they often lack measurable e…
