具有反对称物质的5维$Sp(N)$规范理论的精化拓扑顶点

Refined topological vertex for a 5D $Sp(N)$ gauge theory with antisymmetric matter

Shi Cheng, Sung-Soo Kim

摘要:

本文考虑具有反对称超多重态和$N_f$基本超多重态的5D $Sp(N)$规范理论的IIB型5膜网图。相应的5-膜可以通过Higgsing一个5-膜网来得到,用于规范规范理论。我们利用改进的拓扑顶点方法计算了具有一个反对称超多重态和味的5D $Sp(2)$理论的Nekrasov配分函数。我们的结果与已知的ADHM方法得到的结果一致。我们还讨论了一个特定的调整Kähler参数与此Higgsing。

英文摘要:

We consider Type IIB 5-brane web diagrams for a 5D $Sp(N)$ gauge theory with an antisymmetric hypermultiplet and $N_f$ fundamental hypermultiplets. The corresponding 5-branes can be obtained by Higgsing a 5-brane web for quiver gauge theory. We use the refined topological vertex formalism to compute Nekrasov partition functions of 5D $Sp(2)$ theories with one antisymmetric hypermultiplet and flavors. Our results agree with the known results obtained from the ADHM method. We also discuss a particular tuning of Kähler parameters associated with this Higgsing.
