Affleck-Dine inflation is a recently proposed model in which a single complex scalar field, nonminimally coupled to gravity, drives inflation and simultaneously generates the baryon asymmetry of universe via Affleck-Dine mechanism. In this paper we investigate the supersymmetric implementation of Affleck-Dine inflation in the use of two chiral superfields with appropriate superpotential and Khler potential. The scalar potential has a similar form to the potential of original Affleck-Dine inflation, and it gives successful inflation and baryogenesis. We also consider the isocurvature perturbation evolving after crossing the horizon, and find that it is ignorable and hence consistent with the observations.

Affleck-Dine 暴胀是最近提出的一个模型，其中一个复杂的标量场与重力非最小耦合，驱动暴胀，同时通过 Affleck-Dine 机制产生宇宙的重子不对称性。在本文中，我们研究了使用具有适当超电势和 Khler 势的两个手性超场的 Affleck-Dine 膨胀的超对称实现。标量势与原始 Affleck-Dine 暴胀势的形式相似，它给出了成功的暴胀和重子发生。我们还考虑了跨越视界后演变的等曲率扰动，并发现它是可忽略的，因此与观察结果一致。
