幂零超场的暴胀与隆升

Inflation and Uplifting with Nilpotent Superfields

Renata Kallosh, Andrei Linde

摘要:

最近,人们发现,如果一些标准的、无约束的手征超场被与超对称性相关的幂零超场所取代,那么现有的基于超引力的暴胀模型中的一大类可以被显著简化。同样的方法可以简化弦论中现有的AdS真空上升模型。在本文中,我们将表明,人们可以远远超出简化已经存在的模型。我们将提出一个广泛的新模型的混沌膨胀的基础上超引力与幂零超场,同时纳入通货膨胀和隆起。他们提供了一个简单的统一描述的膨胀和目前的加速度的宇宙在超引力的背景下。

英文摘要:

Recently it was found that a broad class of existing inflationary models based on supergravity can be significantly simplified if some of the standard, unconstrained chiral superfields are replaced by nilpotent superfields, associated with Volkov-Akulov supersymmetry. The same method allows to simplify the existing models of uplifting of AdS vacua in string theory. In this paper we will show that one can go well beyond simplifying the models that already exist. We will propose a broad class of new models of chaotic inflation based on supergravity with nilpotent superfields, which simultaneously incorporate both inflation and uplifting. They provide a simple unified description of inflation and the present acceleration of the universe in the supergravity context.
