Title: Axion inflation and Affleck-Dine baryogenesis

Abstract

String theory generically predicts the coupling between the Affleck-Dine field and axion field through higher-dimensional operators. We thus explore the Affleck-Dine baryogenesis on an axion background. It turns out that the axion oscillation produces an enough amount of baryon asymmetry of the Universe just after the inflation, even without a soft supersymmetry-breaking A -term. This baryogenesis scenario is applicable to the string axion inflation.
