通过5d瞬子、qW-algebrae和(1,0)超共形指数增强对称性

Symmetry enhancements via 5d instantons, qW-algebrae and (1,0) superconformal index

Sergio Benvenuti, Giulio Bonelli, Massimiliano Ronzani, Alessandro Tanzini

摘要:

我们研究了由M5-膜探测横向A_k奇点而产生的N=(1,0)超共形六维理论。在5维圆紧化后,我们用一个五膜的双pq网描述了这个系统,并提出了驱动全局对称性增强的基本五维瞬子算子的谱。对于单个M5-膜,我们发现5d规范规范理论的精确配分函数与6d(1,0)指数相匹配,这是我们通过字母计数计算的。最后证明了pq-网的S-对偶蕴含了qW-代数的顶点扩张子之间的新关系。

英文摘要:

We explore N=(1,0) superconformal six-dimensional theories arising from M5-branes probing a transverse A_k singularity. Upon circle compactification to 5 dimensions, we describe this system with a dual pq-web of five-branes and propose the spectrum of basic five-dimensional instanton operators driving global symmetry enhancement. For a single M5-brane, we find that the exact partition function of the 5d quiver gauge theory matches the 6d (1,0) index, which we compute by letter counting. We finally show that S-duality of the pq-web implies new relations among vertex correlators of qW-algebrae.
