A swamp of non-SUSY vacua

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 de...

Zusammenfassung: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.
