SuperWimp Baryogenesis — •Giorgio Arcadi — University of Goettingen, Friedrich-Hund-Platz 1, Goettingen, Germany

I will discuss the possibility for a common and contemporary generation of the baryon asymmetry and of the Dark Matter content of the Universe through the SuperWimp mechanism, namely the out-of-equilibrium decay of a mother particle. Although this mechanism can be effective in general particle physics frameworks, a natural playground is constituted by the Supersymmetric extensions of the Standard Model with gravitino Dark Matter. I will present several realizations of the mechanism featuring the generation of Dark Matter and baryon asymmetry at the Electroweak scale as well as at very high scales, typical of the popular thermal leptogenesis scenarios.
