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…
Dynamics of Self-Interacting Dark Sectors
Esau Cervantes
This thesis investigates the dynamics of self-interacting dark sectors in the early Universe populated through the freeze-in mechanism. The main focus is on scenarios with self-num…
KineticXGPU: A Tensorized Collision Operator for Dark-Sector Self-Scattering
Esau Cervantes
In this work, we present KineticXGPU, a PyTorch-based implementation of the elastic self-collision operator for dark-sector momentum distributions. The discretized collisi…
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)…
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…
