L级无质量超对称阶梯

The massless supersymmetric ladder with L rungs

G. C. Rossi, Ya . S. Stanev

摘要:

我们表明,在无质量N=1超对称Wess-Zumino理论中,可以设计一种计算策略,通过该策略,可以在不引入任何正则化的情况下进行梯形4点算子的x空间计算。作为一个应用程序,我们推导出一个有效的表示在所有循环订单的共形不变积分。我们得到了共线外点的三圈梯形图的一个显式表达式。

英文摘要:

We show that in the massless N=1 supersymmetric Wess-Zumino theory it is possible to devise a computational strategy by which the x-space calculation of the ladder 4-point correlators can be carried out without introducing any regularization. As an application we derive a representation valid at all loop orders in terms of conformal invariant integrals. We obtain an explicit expression of the 3-loop ladder diagram for collinear external points.
