Abstract

We present a new gauging of maximal supergravity in five spacetime dimensions with gauge group containing ISO(5), involving the local scaling symmetry of the metric, and admitting a supersymmetric anti–de Sitter vacuum. We show this maximal supergravity to arise by consistent truncation of M theory on the (nonspherical, nonparallelizable) six-dimensional geometry associated to a stack of N M5 branes wrapped on a smooth Riemann surface. The existence of this truncation allows us to holographically determine the complete, universal spectrum of light operators of the dual four-dimensional N=2 theory of class S. We then compute holographically the superconformal index of the dual field theory at large N, finding perfect agreement with previously known field theory results in specific limits.

最大超重力的S类超共形指数

我们提出了一种包含ISO(5)的测度群在五时空维度上的最大超重力的新测度，涉及到测度的局部标度对称，并承认一个超对称的反德西特真空。我们通过M理论在（非球面，不可并行化）六维几何上的一致截断来证明这种最大超重力的产生，该几何与光滑黎曼表面上包裹的N个M5膜的堆栈有关。这种截断的存在使我们能够全息地确定s类的对偶四维N=2理论的光算符的完整的普适谱。然后，我们全息地计算了对偶场论在大N处的超共形折射率，在特定的极限上与先前已知的场论结果完全一致。2025年由美国物理学会出版
