Leptogenesis after chaotic sneutrino inflation and the supersymmetry breaking scale

We discuss resonant leptogenesis arising from the decays of two nearly-degenerate right-handed neutrinos, identified as the inflaton and stabiliser superfields in a model of chaotic sneutrino inflation. We compare an analytical estimate of the baryon asymmetry ηB in the Boltzmann approximation to a...
