从2d/4d指标看杂种优势的表面缺陷和对偶性

Heterotic Surface Defects and Dualities from 2d/4d Indices

Heng-Yu Chen, Hsiao-Yi Chen

摘要:

从超共形指数的4d N=2和N=1超对称规范理论,这是相关的超势变形,我们执行的轮廓积分和隔离的残留的贡献,可以归因于表面缺陷。这些缺陷可以解释为动力学涡旋的IR极限。给定这些表面缺陷的2d N=(2,2)和N=(0,2)世界片理论,我们通过明确计算它们的椭圆属和通过超共形代数确定它们的逸度参数来验证这一说法.我们表明,它们精确匹配,结果扩展到4D超对称配分函数插入表面缺陷到N=1设置以前的处方。我们还研究了4d N=1 IR对偶如何下降到N=(0,2)世界片理论的表面缺陷,并延长了N=(2,2)triality先前观察到的其他N=(0,2)表面缺陷无关的动力学涡旋。

英文摘要:

Starting with the superconformal indices for 4d N=2 and N=1 supersymmetric gauge theories, which are related by superpotential deformation, we perform the contour integrations and isolate the residue contributions which can be attributed to the surface defects. These defects can be interpreted as the IR limit of dynamical vortices. Given the 2d N=(2,2) and N=(0,2) world sheet theories for these surface defects, we then verify this statement by explicitly computing their elliptic genera and identifying their fugacity parameters through superconformal algebras. We show them precisely match, and the results extend previous prescriptions for inserting surface defects into 4d supersymmetric partition functions to N=1 setting. We also study how 4d N=1 IR dualities descend into the N=(0,2) world sheet theories of their surface defects, and extend the N=(2,2) triality observed earlier to other N=(0,2) surface defects unrelated to dynamical vortices.
