我证明，通过蒙特卡罗程序中簇射算法的简单扩展，可以对最困难的发射实施 NLO 校正，从而克服先前实现中发现的负权重事件的问题。同一方法的简单变体可用于改进 Shower Monte Carlo 程序中矩阵元素校正的处理。
I show that with simple extensions of the shower algorithms in Monte Carlo programs, one can implement NLO corrections to the hardest emission that overcome the problems of negative weighted events found in previous implementations. Simple variants of the same method can be used for an improved treatment of matrix element corrections in Shower Monte Carlo programs.
