N=2规范理论与Toda理论的简并场

N=2 gauge theories and degenerate fields of Toda theory

Shoichi Kanno, Yutaka Matsuo, Shotaro Shiba, Yuji Tachikawa

摘要:

本文讨论了W_N代数的简并场与N=2超共形规范理论的Seiberg-Witten曲线的Gaiotto描述的穿刺之间的对应关系。也就是说,我们发现在第一层具有零态的W_N代数的简并场的类型可以用N盒的Young图来分类,并且在穿刺点附近Seiberg-Witten曲线的奇异性与W_N生成元的奇异性一致。我们还发现如何翻译的质量参数的规范理论的Toda理论的动量。

英文摘要:

We discuss the correspondence between degenerate fields of the W_N algebra and punctures of Gaiotto's description of the Seiberg-Witten curve of N=2 superconformal gauge theories. Namely, we find that the type of degenerate fields of the W_N algebra, with null states at level one, is classified by Young diagrams with N boxes, and that the singular behavior of the Seiberg-Witten curve near the puncture agrees with that of W_N generators. We also find how to translate mass parameters of the gauge theory to the momenta of the Toda theory.
