Coulomb and Higgs Branches from Canonical Singularities: Part 0

Cyril Closset, Sakura Schafer-Nameki, Yi-Nan Wang

摘要:

五维和四维超共形场论分别由M理论和IIB型弦论中的正则三重奇点产生。我们研究了它们的库仑和希格斯分支使用crepant分辨率和变形的奇异性。我们提出了一个模空间之间的关系,紧化的理论,以3D,其次是3D $\mathcal{N}=4$镜像对称和$S$型计量的阿贝尔味对称。特别是,我们使用这种对应关系,以确定希格斯分支的一些5d SCFT和他们的磁颤炮的几何形状。作为一般框架的应用,我们观察到,工程师的Argyres-Douglas理论在IIB型的奇点也引起了秩0 5d SCFT在M理论。我们还计算了4d和5d SCFT的高阶对称性,包括$(G, G')$型广义Argyres-Douglas理论的一种对称性。

英文摘要:

Five- and four-dimensional superconformal field theories with eight supercharges arise from canonical threefold singularities in M-theory and Type IIB string theory, respectively. We study their Coulomb and Higgs branches using crepant resolutions and deformations of the singularities. We propose a relation between the resulting moduli spaces, by compactifying the theories to 3d, followed by 3d $\mathcal{N}=4$ mirror symmetry and an $S$-type gauging of an abelian flavor symmetry. In particular, we use this correspondence to determine the Higgs branch of some 5d SCFTs and their magnetic quivers from the geometry. As an application of the general framework, we observe that singularities that engineer Argyres-Douglas theories in Type IIB also give rise to rank-0 5d SCFTs in M-theory. We also compute the higher-form symmetries of the 4d and 5d SCFTs, including the one-form symmetries of generalized Argyres-Douglas theories of type $(G, G')$.
