论文摘要
Affleck-dine通货膨胀是一个最近提出的模型,在该模型中,单个复杂的标量场(非最小程度耦合到重力),驱动通货膨胀并同时通过Affleck-Dine机制产生宇宙的Baryon不对称性。在本文中,我们调查了使用两个具有适当超电势和Kähler潜力的手性超级场地的Affleck-dine通货膨胀的超对称实施。标量电势具有与原始Affleck-Dine通货膨胀潜力相似的形式,并提供了成功的通货膨胀和重生生成。我们还考虑了越过地平线后发生的等化扰动,并发现它是可忽视的,因此与观测值一致。
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 Kähler 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.
