论文摘要

我们研究了超对称性本质上非线性实现的超级对称理论,仅由四型通量支持。我们证明可以通过戈德斯蒂诺多重蒸发来恢复超对称性。这样的过程要求根据WGC存在超级2元的超级2-大国,并提出了Sitter Supergravity中的即将发生的衰变,使该系统在过渡后放置在超对称广告中。特别是,相同的衰减机制也意味着KKLT DE Sitter Vacua是短暂的。因此,我们的发现提供了4D超级衰减的KPV型型的有效实现,通过这种方式可以使De Sitter的Nilpotent Superfield构造与Swampland程序的某些方面进行调和。

We study supergravity theories with supersymmetry intrinsically non-linearly realized supported only by four-form flux. We demonstrate that supersymmetry can be restored by the evaporation of the goldstino multiplet. Such procedure requires the existence of a super-extremal 2-brane, in accordance with the WGC, and suggests an imminent decay in de Sitter supergravity, leaving the system to relax in supersymmetric AdS after the transition. In particular, the same decay mechanism also implies that the KKLT de Sitter vacua are short-lived. Our findings thus provide an effective realization of KPV-type of decays within 4D supergravity and in this way may reconcile the nilpotent superfield constructions of de Sitter with some aspects of the swampland program.
