紧Riemann曲面上M-膜上的线算子

Line operators from M-branes on compact Riemann surfaces

Antonio Amariti, Domenico Orlando, Susanne Reffert

摘要:

本文确定了包裹在紧Riemann曲面上的M5-膜上的S类理论的相互定域Wilson和t Hooft线算子的荷格。我们分析的主要成分是黎曼曲面的N-覆盖的基本群,以及对六维理论的量子约束。后者在排除一些可能的格和对电荷施加一致性条件方面起着核心作用。这种结构给出了线之间的相互定域性的几何解释,固定了它们的电荷晶格和四维规范群的结构。

英文摘要:

In this paper, we determine the charge lattice of mutually local Wilson and 't Hooft line operators for class S theories living on M5-branes wrapped on compact Riemann surfaces. The main ingredients of our analysis are the fundamental group of the N-cover of the Riemann surface, and a quantum constraint on the six-dimensional theory. This latter plays a central role in excluding some of the possible lattices and imposing consistency conditions on the charges. This construction gives a geometric explanation for the mutual locality among the lines, fixing their charge lattice and the structure of the four-dimensional gauge group.
