In this note we discuss the classification of duality orbits of N=8 gauged supergravity models. Using tensor classifiers, we show that there is a one-parameter family of inequivalent SO(8) gauged supergravity theories. We briefly discuss the couplings of such models and show that, although the maximally symmetric vacuum has the same quadratic spectrum, the supersymmetry transformations, the couplings, and the scalar potential are parameter dependent. We also comment on the possible M theory uplift and on the meaning of the parameter for the dual gauge theories.
在本注释中，我们讨论了 N=8 规范超引力模型的对偶轨道分类。使用张量分类器，我们表明存在一个不等价的 SO(8)规范超引力理论的单参数族。我们简要讨论了这些模型的耦合，并表明尽管最大对称真空具有相同的二次谱，但超对称性变换、耦合和标量势是参数相关的。我们还对可能的 M 理论提升以及对偶规范理论中参数的意义进行了评论。
