我们开始研究一类四维=2超共形场论的全息对偶，这种场论是通过将M5膜包裹在具有不规则穿孔的球面上而实现的。其中包括Argyres-Douglas类型的强耦合场论。我们的解是在7D测量的超重力中得到的，它们的形式是ADS 5的翘曲产物和一个“半心轴”。不规则穿透由重力对偶内部空间的局部M5膜源模拟。我们的解具有不同于通常的拓扑扭曲的超对称性的实现，以及一个有趣的Stükerelberg机制，该机制涉及与内部空间的等距代数的生成器相关联的规范场。我们通过计算全息中心电荷、味道对称中心电荷和各种超对称探测M2膜的尺寸，并将其与对偶Argyres-Douglas场论相匹配来验证所提出的对偶性。此外，我们用M理论中的反常流入方法计算了场论的大N‘t Hooft反常，发现与所提出的对偶性完全一致。
We initiate a study of the holographic duals of a class of four-dimensional= 2 superconformal field theories that are engineered by wrapping M5-branes on a sphere with an irregular puncture. These notably include the strongly-coupled field theories of Argyres-Douglas type. Our solutions are obtained in 7d gauged supergravity, where they take the form of a warped product of AdS 5 and a “half-spindle.” The irregular puncture is modeled by a localized M5-brane source in the internal space of the gravity duals. Our solutions feature a realization of supersymmetry that is distinct from the usual topological twist, as well as an interesting Stückelberg mechanism involving the gauge field associated to a generator of the isometry algebra of the internal space. We check the proposed duality by computing the holographic central charge, the flavor symmetry central charge, and the dimensions of various supersymmetric probe M2-branes, and matching these with the dual Argyres-Douglas field theories. Furthermore, we compute the large-N’t Hooft anomalies of the field theories using anomaly inflow methods in M-theory, and find perfect agreement with the proposed duality.
