Title:
Exponentially Growing Dark Matter
Speaker:
Abstract:
The dark matter abundance may have experienced a period of exponential growth in the early Universe. This is a generic possibility if dark matter is non-thermal and if it experiences scattering processes converting one dark matter particle into two (or more) dark matter particles. I will show new parameter space for sterile neutrino dark matter, where active neutrinos oscillate into an initially small abundance of sterile neutrinos that then exponentially grows.
