非平凡背景下的关联函数

Correlators in Nontrivial Backgrounds

Robert de Mello Koch, Norman Ives, Michael Stephanou

摘要:

在N=4的超杨-米尔斯理论中,R-荷为O(N^2)的算子与背景是对称的AdS 5xS 5。在这篇文章中,我们开发了有效的技术,允许在这些背景下的关联函数的计算。我们发现:(i)弦字中的场与产生背景的算符中的场之间的压缩是新几何的场论解释,(ii)这些背景中探针的关联函数由自由场论压缩给出,但具有重标度传播子,(iii)在这些背景中不存在具有特殊端点相互作用的开弦激发;我们只有闭合弦激发。

英文摘要:

Operators in N=4 super Yang-Mills theory with an R-charge of O(N^2) are dual to backgrounds which are asymtotically AdS5xS5. In this article we develop efficient techniques that allow the computation of correlation functions in these backgrounds. We find that (i) contractions between fields in the string words and fields in the operator creating the background are the field theory accounting of the new geometry, (ii) correlation functions of probes in these backgrounds are given by the free field theory contractions but with rescaled propagators and (iii) in these backgrounds there are no open string excitations with their special end point interactions; we have only closed string excitations.
