Self-interacting dark matter with a stable vector mediator

24 Sep 2018 Duerr Michael Schmidt-Hoberg Kai Wild Sebastian

Light vector mediators can naturally induce velocity-dependent dark matter self-interactions while at the same time allowing for the correct dark matter relic abundance via thermal freeze-out. If these mediators subsequently decay into Standard Model states such as electrons or photons however, this is robustly excluded by constraints from the Cosmic Microwave Background... (read more)
