N = 1规范理论中的微观量子超势

Microscopic quantum superpotential in N=1 gauge theories

Frank Ferrari

摘要:

本文研究了N = 1的超杨-米尔斯理论,其规范群为U(N),伴随手征多重态为X,超势为Tr W(X).我们计算了标量场X的量子有效超势W_mic随无穷远处任意离壳边界条件的变化。这个有效超势有一个显著的性质:它的临界点与理论的量子真空全集一一对应,特别是为低能规范群提供了不同秩解的统一图像。从这个意义上说,W_mic是一个很好的微观有效量子超势.这种性质并不被文献中常用的其他量子有效超势所共有,比如强耦合方法或胶球超势。本文的结果是将Nekrasov关于N = 2超杨-米尔斯理论的Seiberg-Witten解的微观推导推广到N = 1规范理论的第一步。

英文摘要:

We consider the N=1 super Yang-Mills theory with gauge group U(N), adjoint chiral multiplet X and tree-level superpotential Tr W(X). We compute the quantum effective superpotential W_mic as a function of arbitrary off-shell boundary conditions at infinity for the scalar field X. This effective superpotential has a remarkable property: its critical points are in one-to-one correspondence with the full set of quantum vacua of the theory, providing in particular a unified picture of solutions with different ranks for the low energy gauge group. In this sense, W_mic is a good microscopic effective quantum superpotential for the theory. This property is not shared by other quantum effective superpotentials commonly used in the literature, like in the strong coupling approach or the glueball superpotentials. The result of this paper is a first step in extending Nekrasov's microscopic derivation of the Seiberg-Witten solution of N=2 super Yang-Mills theories to the realm of N=1 gauge theories.
