We propose a mechanism by which density perturbations δρ/ρ∼10-4 and a baryon asymmetry nB/s10-10 can naturally be generated in any realistic supersymmetric theory. By ‘‘naturally’’ we mean that the coefficient λ in the usual toy-model inflationary potential Vφ4 is related to the superpotential Yukawa coupling λe which generates the electron mass. We identify a nine-parameter ‘‘quasiflat’’ direction which generates δρ/ρ through chaotic inflation and which leads to an Affleck-Dine valley (flat direction) where primordial baryogenesis occurs.
