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…

Phase Transitions and Gravitational Waves in a Model of Scalar Dark Matter

Nico Benincasa, Andrzej Hryczuk, Kristjan Kannike +1

Theories with more than one scalar field often exhibit phase transitions producing potentially detectable gravitational wave (GW) signal. In this work we study the semi-annihilatin…
