论文摘要
对于动作中的某些术语，超对称性可以禁止无限数量的可能贡献。我们研究即使没有足够的超对称性，量子重力也可以发生。我们关注的是超电势是否可以在四维n = 1理论中完全消失，并且如果预势可以在n = 2理论中恰好是立方体。我们在字符串理论中调查了这些问题，并发现对于几乎所有已知的弦构造，Supersymmemery允许的校正确实会发生。但是，我们确实找到了一些特殊的设置，可以证明所有更正可以消失。这些示例都共享了它们通过离散测量的R-对称元件与更高的超对称理论相关的一定特征，即它们相关的特征。在这些结果的推动下，我们提出了一个骗局标准，即任何具有这种保护的理论超出其实现的超对称性，都必须与更高的超对称理论有直接的联系。
For certain terms in the action, supersymmetry can forbid an infinite number of possible contributions. We study whether such protection can occur in quantum gravity even without sufficient supersymmetry. We focus on whether the superpotential can vanish exactly in four-dimensional N=1 theories, and if the prepotential can be exactly cubic in N=2 theories. We investigate these questions in string theory and find that for almost all known string constructions the corrections allowed by supersymmetry do occur. However, we do find some special settings where all the corrections can be proven to vanish. These examples all share the common feature that they are related, through a certain orbifolding by a discrete gauged R-symmetry element, to a higher supersymmetric theory. Motivated by these results, we propose a Swampland criterion that any theory which enjoys such protection beyond its realised supersymmetry must have a direct connection to a higher supersymmetric theory.
