提出了一种基于 OPP 约简方法的算法，可以自动计算外部粒子的所有动量、颜色和螺旋度配置的任何单环振幅。它是使用树序矩阵元素代码 HELAC 和 OPP 简化代码 CutTools 实现的。为了展示当前实施的潜力，列出了 2007 年 Les Houches 大型强子对撞机愿望清单中包含的所有子流程的结果。
An algorithm, based on the OPP reduction method, to automatically compute any one-loop amplitude, for all momentum, color and helicity configurations of the external particles, is presented. It has been implemented using the tree-order matrix element code HELAC and the OPP reduction code CutTools. As a demonstration of the potential of the current implementation, results for all sub-processes included in the 2007 Les Houches wish list for LHC, are presented.
