A case for calculating dark matter momentum distribution
Andrzej Hryczuk, NCBJ
Event Type: Informal HEP Talk
Time: 11:00 AM - 12:15 PM
Location: 726 Broadway, 940, CCPP Seminar
Abstract: The process of thermal production, both freeze-in and freeze-out, can be significantly more complex and richer than the usual simple description tells us. In this talk, I will discuss some of the recent progress in understanding the impact of non-equilibrium effects on particle production, whether it be the dark matter itself or other states in the dark sector. Consequences of performing the calculation taking into account non-equilibrium distributions will be highlighted. I will also show how cannibal-type processes can cool down warm dark matter, alleviating a bit the Lyman-alpha limits.
