Description
In pangenesis, the baryon asymmetry of the universe and the dark
matter abundance are generated simultaneously via the Affleck-Dine
mechanism. This talk will discuss the Affleck-Dine dynamics, both for the case of gravity- and gauge-mediated supersymmetry breaking. Cosmological constraints on the scenario, in particular arising from the production of gravitinos and the formation of Q-balls, will be considered and the viable regions of parameter space for successful pangenesis presented. The results are also applicable to other scenarios involving the Affleck-Dine mechanism.
