论文摘要
We compute the Kaluza-Klein spectrum of the non-supersymmetric SO(3)$\,\times\,$SO(3)-invariant AdS$_4$ vacuum of 11-dimensional supergravity, whose lowest-lying Kaluza-Klein modes belong to a consistent truncation to 4-dimensional ${\cal N}=8$ supergravity and是稳定的。我们表明，尽管如此，较高的kaluza-klein模式就会成为速旋，因此这种非苏匹配广告$ _4 $ $ _4 $ vacuum在11维超级强度范围内呈扰动。这代表了不稳定的较高kaluza-klein模式的第一个例子，并为ADS Swampland猜想提供了进一步的证据，该猜想指出，在字符串理论中没有稳定的非superymmetric Ads真空吸尘器。我们还发现了Kaluza-Klein模式中的27个无限模量，这暗示着存在非苏格米对称广告的家族$ _4 $ _4 $ vacua。
We compute the Kaluza-Klein spectrum of the non-supersymmetric SO(3)$\,\times\,$SO(3)-invariant AdS$_4$ vacuum of 11-dimensional supergravity, whose lowest-lying Kaluza-Klein modes belong to a consistent truncation to 4-dimensional ${\cal N}=8$ supergravity and are stable. We show that, nonetheless, the higher Kaluza-Klein modes become tachyonic so that this non-supersymmetric AdS$_4$ vacuum is perturbatively unstable within 11-dimensional supergravity. This represents the first example of unstable higher Kaluza-Klein modes and provides further evidence for the AdS swampland conjecture, which states that there are no stable non-supersymmetric AdS vacua within string theory. We also find 27 infinitesimal moduli amongst the Kaluza-Klein modes, which hints at the existence of a family of non-supersymmetric AdS$_4$ vacua.
