AdS_5超重力中的R流六点关联函数

R-current six-point correlators in AdS_5 Supergravity

J. Bartels, J. Kotanski, A. -M. Mischler, V. Schomerus

摘要:

在N = 4的超杨-米尔斯和Anti-deSitter弦论之间的约束对偶中,规范理论的BFKL波密子对应于对偶弦的引力子模。作为分析多重引力子交换的第一步,我们研究了超引力近似下的R流六点函数。我们计算了衍射散射的模拟,并分析了三重Regge极限。在超引力近似下,三重引力子顶点消失。

英文摘要:

Within the conjectured duality between N=4 super Yang-Mills and Anti-deSitter string theory, the BFKL Pomeron of the gauge theory corresponds to the graviton mode of the dual string. As a first step towards analyzing multigraviton exchange, we investigate R-current six-point functions within the supergravity approximation. We compute the analogue of diffractive scattering, and we analyze the triple Regge limit. In the supergravity approximation the triple graviton vertex is found to vanish.
