Four-point correlation function of stress-energy tensors in N=4 superconformal theories

G. P. Korchemsky, E. Sokatchev

摘要:

在四维N=4超共形理论中,导出了应力-能量张量四点关联函数的显式表达式。我们表明,它有一个非常简单和暗示的形式,使我们能够预测一个大类的四点关联函数涉及的应力-能量张量和其他守恒电流。然后,我们应用所获得的结果的关联函数计算的能量-能量的相关性,它测量的能量流的最终状态从真空中创建的源。我们证明,它们是由一个通用的功能独立的源的选择。我们的分析只依赖于N=4的超共形对称性,而不使用理论的动力学。

英文摘要:

We derive the explicit expression for the four-point correlation function of stress-energy tensors in four-dimensional N=4 superconformal theory. We show that it has a remarkably simple and suggestive form allowing us to predict a large class of four-point correlation functions involving the stress-energy tensor and other conserved currents. We then apply the obtained results on the correlation functions to computing the energy-energy correlations, which measure the flow of energy in the final states created from the vacuum by a source. We demonstrate that they are given by a universal function independent of the choice of the source. Our analysis relies only on N=4 superconformal symmetry and does not use the dynamics of the theory.
