标题： Inflation with large supergravity corrections

摘要： 众所周知，大尺度的哈勃诱导超引力修正会对暴胀场产生影响，从而破坏势能的平坦性，因此在慢滚暴胀和超引力之间产生了张力。 本文中我们展示了即便存在非常大的超哈勃修正，仍然可以在最小超对称标准模型内获得一个{\it 宇宙学平坦}方向。 作为例子，我们展示了被$n=6$算符提升的平坦方向对于哈勃参数的广泛范围（$10^{5} {\rm GeV}\lesssim H_{inf}\lesssim 10^{8.5}$GeV）与当前宇宙微波背景数据一致。 我们的方法可以应用于任何$F$项暴胀模型。 显示英文摘要

摘要： It is well known that large Hubble-induced supergravity corrections to the inflaton field can ruin the flatness of the potential, thus creating a tension between slow-roll inflation and supergravity. In this paper we show that it is possible to obtain a {\it cosmologically flat} direction, embedded within the minimal supersymmetric standard model, despite very large super-Hubble corrections. As an illustration, we show that a flat direction which is lifted by an $n=6$ operator matches the current cosmic microwave background data for a wide range of the Hubble parameter, $10^{5} {\rm GeV}\lesssim H_{inf}\lesssim 10^{8.5}$ GeV. Our approach can be applied to any $F$-term inflationary model.
