Description
In this talk, I will present a dark matter model in which both the dark sector and the visible sector share a common asymmetry. This asymmetry is mediated by an unstable dark particle of baryon number one through a semi-annihilation process. We realize a viable parameter space in which we find (1) the correct dark matter abundance, (2) the correct baryon asymmetry, and (3) a plausible dark matter interpretation for the Fermi GeV excess. This model provides a proof-of-concept that fully asymmetric dark matter can still lead to interesting indirect detection signals.
