非超对称真空的沼泽

A swamp of non-SUSY vacua

U. H. Danielsson, G. Dibitetto, S. C. Vargas

摘要:

我们考虑已知的例子,非超对称的AdS $_7$和AdS $_4$解决方案所产生的大规模IIA型超引力的紧化和研究其稳定性,考虑到封闭和开放的字符串扇区之间的耦合激发。一般来说,开弦被发现发展模式的质量低于Breitenlohner-Freedman(BF)界限。我们评论与弱引力猜想的关系,以及这种分析如何在检验弦论中非超对称结构的有效性方面发挥重要作用。

英文摘要:

We consider known examples of non-supersymmetric AdS$_7$ and AdS$_4$ solutions arising from compactifications of massive type IIA supergravity and study their stability, taking into account the coupling between closed- and open-string sector excitations. Generically, open strings are found to develop modes with masses below the Breitenlohner-Freedman (BF) bound. We comment on the relation with the Weak Gravity Conjecture, and how this analysis may play an important role in examining the validity of non-supersymmetric constructions in string theory.
