Two critical problems are the origin of the baryon asymmetry and the nature of dark matter. In this talk, I will present a minimal, renormalizable model for baryogenesis in which both the dark and standard-model matter asymmetries originate from the same mechanism: electroweak-like baryogenesis in a dark “mirror” sector. In addition to outlining the model and the baryogenesis mechanism, this talk will also explore the dark matter phenomenology and detection prospects at present and future experiments.
