Scientific paper

We show that the Ωb - ΩDM coincidence can naturally be explained in a framework where axino cold dark matter is predominantly produced in non-thermal processes involving decays of Q-balls formed in Affleck-Dine baryogenesis. In this approach the similarity between Ωb and ΩDM is a direct consequence of the (sub-)GeV scale of the mass of the axino.
