摘要：
Affleck-Dine baryogenesis is preconditioned on a certain structure of nonrenormalizable operators in the Kähler potential. In this paper, we geometrically characterize the resulting constraint on the field space Kähler geometry and survey the Lagrangian for correlated predictions. The Affleck-Dine field backreacts on the inflaton, and by mapping the backreacted potential to an inflaton potential with a step, we find that current CMB data severely constrain some versions of the scenario.
