超对称规范理论与Yangian

Supersymmetric gauge theory and the Yangian

Kevin Costello

摘要:

本文发展了超对称规范理论与Yangian之间的一种新的联系。我表明,一个扭曲的,变形版本的纯N = 1超对称规范理论的控制杨,以同样的方式,陈-西蒙斯理论控制的量子群。这个结果被用来在微扰论中精确计算变形N = 1规范理论中n + m个Wilson算符的网络的期望值。这个期望值与n × m双周期晶格上自旋链可积晶格模型的配分函数相一致。

英文摘要:

This paper develops a new connection between supersymmetric gauge theories and the Yangian. I show that a twisted, deformed version of the pure N=1 supersymmetric gauge theory is controlled by the Yangian, in the same way that Chern-Simons theory is controlled by the quantum group. This result is used to give an exact calculation, in perturbation theory, of the expectation value of a certain net of n+m Wilson operators in the deformed N=1 gauge theory. This expectation value coincides with the partition function of a spin-chain integrable lattice model on an n-by-m doubly-periodic lattice.
