弱耦合下N = 4 SYM中R-电流在Regge极限下的四点函数

Four point function of R-currents in N=4 SYM in the Regge limit at weak coupling

J. Bartels, A. -M. Mischler, M. Salvadore

摘要:

本文在N = 4的超Yang-Mills理论中,在弱耦合的情况下,采用对数近似,计算了R流在Regge极限下的四点关联函数。这种相关器是量子色动力学中最接近光子-光子散射的模拟,并且有一个定义明确的过程来通过AdS/CFT对应在强耦合下进行类似的计算。本文的主要结果是在规范理论方面证明了Regge因子分解并计算了R流影响因子。

英文摘要:

We compute, in N=4 super Yang-Mills theory, the four point correlation function of R-currents in the Regge limit in the leading logarithmic approximation at weak coupling. Such a correlator is the closest analog to photon-photon scattering within QCD, and there is a well-defined procedure to perform the analogous computation at strong coupling via the AdS/CFT correspondence. The main result of this paper is, on the gauge theory side, the proof of Regge factorization and the explicit computation of the R-current impact factors.
