Asymmetric WIMP Dark Matter in the presence of DM/anti-DM OscillationsGabrijela Zaharijas, 2012, objavljeni povzetek znanstvenega prispevka na konferenci
Opis: 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 densities
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 reopen
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.
