Description
In this talk, I will discuss scenarios where dark matter is uncharged under the Standard Model (SM) gauge symmetry but can carry baryon and/or lepton number and hence also an asymmetry. The baryon and/or lepton number of dark matter is defined through its coupling to the SM fields. The strength of the coupling determines how the asymmetry is shared among the dark matter and the SM fields. After chemical decoupling, the two sectors barely talk to each other. In this scenario, dark matter can be as light as GeV or as heavy as 1000 TeV. I will discuss phenomenological constraints on such scenarios.
