关于低秩4d $\mathcal{N}=2$超共形场论

On low rank 4d $\mathcal{N}=2$ SCFTs

Bohan Li, Dan Xie, Wenbin Yan

AI总结:

本文系统搜索了由class-S理论和IIB弦论构造的所有低秩4d N=2超共形场论,给出秩的普适公式并计算了中心荷、味对称性等物理量,进而预言了多个新的2d顶点算子代数同构。

摘要:

构造4d $\mathcal{N}=2$超共形场论(SCFT)有两种主要方法:第一种是将6d $(2,0)$理论置于带穿孔的黎曼曲面上(class-S理论),第二种是将IIB型弦理论置于3d标准奇点上。由于人们对低秩理论感兴趣,我们搜索了上述两种构造的所有可能性。这些理论大多由具有不规则奇点的class-S理论构造而成,我们找到了理论秩的普适公式,从而使得完整搜索成为可能。随后,我们计算了这些理论的各种物理量,例如中心荷、味对称性、关联的顶点算子代数以及希格斯分支等。我们结果的一个有趣推论是预言了许多新的2d顶点算子代数同构。

英文摘要:

There are two major ways of constructing 4d $\mathcal{N}=2$ superconformal field theories (SCFTs): the first one is putting a 6d $(2,0)$ theory on a punctured Riemann surface (class-S theory), and the second one is putting type IIB string theory on a 3d canonical singularity. As there are interests on low rank theories, we search all the possibilities from above two constructions. Most of those theories are engineered by class-S theory with irregular singularities, and we find a universal formula for the rank of theory so that a complete search is possible. We then compute various physical quantities of those theories, such as the central charges, flavor symmetry, associated vertex operator algebra and Higgs branch, etc. One of interesting consequence of our results are the prediction of many new isomorphism of 2d vertex operator algebra.
