Laura Covi - Mechanisms for the common origin of Dark Matter and the Baryon Asymmetry

We will discuss two possible ways to generate the Dark Matter and the baryon asymmetry from a single decaying particle, in one case as a co-genesis mechanism in the other within an asymmetric DM scenario. In the first case the DM is very very weakly interacting and decaying, while in latter case a sufficiently strong DM annihilation, possibly due to the Sommerfeld enhancement, is needed to erase the symmetric component. The two models lead to different signatures at colliders, astrophysical measurements and neutrino experiments.
