Asymmetric WIMP Dark Matter in the presence of DM/anti-DM Oscillations

The class of ‘Asymmetric Dark Matter ’ scenarios relies on the existence of a primordial particle/anti-particle asymmetry in the dark sector related to the baryon asymmetry as a way to address the observed similarity between the baryonic and dark matter energy densi-ties today. Focusing on this framework we calculate the evolution of the dark matter relic abundance in the presence of particle/anti-particle oscillations. We show how oscillations re-open the parameter space of asymmetric dark matter models, in particular in the direction of allowing large (WIMP-scale) DM masses. Finally, we constrain the parameter space in this framework by applying up-to-date bounds from indirect detection signals on annihilating DM.
