威尔逊圈:从四维SYM到二维YM

Wilson loops: From four-dimensional SYM to two-dimensional YM

Nadav Drukker, Simone Giombi, Riccardo Ricci, Diego Trancanelli

摘要:

本文研究了N=4的超Yang-Mills空间中限制在S^2子流形上的超对称威尔逊圈.我们从微扰理论和AdS对偶中提供了证据,证明这些环与S^2上二维杨-米尔斯系统中的类似观测量相等(不包括非微扰贡献)。这涉及到一个分区N=4 SYM的低维可溶性模型,也表明,这个分区N =4 SYM是不变的下保持面积同态。

英文摘要:

In this note we study supersymmetric Wilson loops restricted to an S^2 submanifold of four-dimensional space in N=4 super Yang-Mills. We provide evidence from both perturbation theory and the AdS dual that those loops are equal to the analogous observables in two-dimensional Yang-Mills on S^2 (excluding non-perturbative contributions). This relates a subsector of N=4 SYM to a low-dimensional soluble model and also suggests that this subsector of N =4 SYM is invariant under area preserving diffeomorphisms.
