五膜网E弦的表面缺陷

Surface defects on E-string from 5-brane webs

Sung-Soo Kim, Yuji Sugimoto, Futoshi Yagi

摘要:

研究了圆上含缺陷的6维E-弦论。我们的基本策略是将几何跃迁应用于超对称规范理论。首先,我们基于两个不同的5-膜网图计算了与5dSp(2)规范理论UV对偶的5dSU(3)$_0$规范理论的10味配分函数,并检验了两个配分函数是否一致。然后,利用几何跃迁,我们找到了$\mathbb{R}^4\times T^2$上E弦的表面缺陷配分函数。我们还讨论了我们的结果与椭圆亏格的一致性。在此基础上,我们揭示了缺陷是如何破坏整体对称性的,并讨论了破坏模式取决于我们在哪里/如何插入缺陷。

英文摘要:

We study 6d E-string theory with defects on a circle. Our basic strategy is to apply the geometric transition to the supersymmetric gauge theories. First, we calculate the partition functions of the 5d SU(3)$_0$ gauge theory with 10 flavors, which is UV-dual to the 5d Sp(2) gauge theory with 10 flavors, based on two different 5-brane web diagrams, and check that two partition functions agree with each other. Then, by utilizing the geometric transition, we find the surface defect partition function for E-string on $\mathbb{R}^4\times T^2$. We also discuss that our result is consistent with the elliptic genus. Based on the result, we show how the global symmetry is broken by the defects, and discuss that the breaking pattern depends on where/how we insert the defects.
