在已知的具有校准的时空填充源(膜或定向折叠平面)的通量真空的例子中,人们可以涂抹源以执行标准的KK约化并获得较低维的超重力描述。此外,可以预期的是,涂抹和本地化的解决方案保持等量的超对称性。在这篇文章中,我们指出在arXiv:1111.2605和arXiv:1309.2949中讨论的AdS 7解决方案是这个常见知识的一个反例。当充满时空的D 6-膜是局域化的时,解是超对称的,但在模糊极限处打破了超对称性。通过使用嵌入张量形式主义,我们证明了没有规范的超重力描述的解决方案,无论源被涂抹或没有。我们推测,对于流量的解决方案与KK规模和AdS半径之间的分离,这是不可能发生的。
A bstractIn the known examples of flux vacua with calibrated spacetime-filling sources (branes or orientifold planes), one can smear the source in order to perform a standard KK reduction and obtain a lower-dimensional supergravity description. Furthermore, it is expected that the smeared and localized solution preserve equal amounts of supersymmetry. In this note we point out that the AdS7 solution discussed in arXiv:1111.2605 and arXiv:1309.2949 is a counterexample to this common lore. The solution is supersymmetric when the spacetime-filling D6-branes are localized but breaks supersymmetry in the smeared limit. By using the embedding tensor formalism we demonstrate that there is no gauged supergravity description for the solution, regardless of the source being smeared or not. We conjecture that for flux solutions with separation between the KK scale and AdS radius this cannot occur.
