本文对四维空间中最一般的规范$ \mathcal{N}=8 $超引力的G2不变极值进行了详尽的分类。它们包括由单个参数标记的反德西特解决方案的四个分支。有趣的是,当规范群随参数变化时,质谱是不变的。其中之一是一个新的非超对称但稳定的点。我们的分析包括最近提出的SO(8)规范超引力族和更多。
A bstractWe perform an exhaustive classification of G2 invariant extrema of the most general gauged $ \mathcal{N}=8 $ supergravity in four dimensions. They comprise four branches of Anti-de Sitter solutions labelled by a single parameter. Interestingly, while the gauge groups vary with the parameters, the mass spectra are invariant. One of these is a new non-supersymmetric yet stable point. Our analysis includes the recently proposed family of SO(8) gauged supergravities and more.
