N = 4 SYM中反对称Wilson环:从精确结果到非平面修正

Antisymmetric Wilson loops in N = 4 SYM: from exact results to non-planar corrections

Anthonny F. Canazas Garay, Alberto Faraggi, Wolfgang Mück

摘要:

在规范群U(N)或SU(N)的全反对称表象下,研究了N = 4超杨-米尔斯理论中1/2-BPS圆威尔逊圈的真空期望值.局部化和矩阵模型技术为这些期望值提供了精确但相当正式的表达。在本文中,我们展示了如何提取的领先和子领先的行为,在1/N扩展与固定的't Hooft耦合从这些确切的结果。这是通过利用反对称威尔逊圈的生成函数和被称为截断谐振子的有限维量子系统之间的关系来完成的。提供了1/N项的求和和积分表示。

英文摘要:

We consider the vacuum expectation values of 1/2-BPS circular Wilson loops in N=4 super Yang-Mills theory in the totally antisymmetric representation of the gauge group U(N) or SU(N). Localization and matrix model techniques provide exact, but rather formal, expressions for these expectation values. In this paper we show how to extract the leading and sub-leading behavior in a 1/N expansion with fixed 't Hooft coupling starting from these exact results. This is done by exploiting the relation between the generating function of antisymmetric Wilson loops and a finite-dimensional quantum system known as the truncated harmonic oscillator. Sum and integral representations for the 1/N terms are provided.
