摘要: We propose that the inflaton is coupled to ordinary matter only gravitationally and it decays into a completely hidden sector. In this scenario both baryonic dark originate from decay of flat direction minimal supersymmetric standard model, which shown generate desired adiabatic perturbation spectrum via curvaton mechanism. The requirement energy density along dominates over products fixes almost uniquely. present residual in sector typically be small.
