Towards the robustness of Affleck-Dine mechanism

Abstract

In this talk we considered the Affleck-Dine mechanism with various types of the Kahler potential, and investigate whether or not the Affleck-Dine field could acquire a large VEV as an initial condition for successful baryogenesis. In addition to a negative Hubble-induced mass term, we found examples that large enough Hubble-induced A-terms could also develop the minima at large amplitude of the field. It is concluded, therefore, that the Affleck-Dine mechanism works for broader classes of the theories. This talk is based on Ref.[1]. Here I extend the discussion from more generic standpoint, and find that essentially there are three cases that large enough A terms develop minima at large field values.
