摘要:

本文计算了强子对撞机上荷电三矢量玻色子产生过程pp -> ZZW + X和pp -> WWW + X的O(alpha_s)QCD修正。中间希格斯玻色子交换效应,轻子矢量玻色子衰变的自旋相关,和离壳贡献都考虑在内。结果是在一个完全灵活的蒙特卡罗程序,允许一个简单的定制的运动学切割和变化的因式分解和重整化尺度。我们分析了尺度变化下的微分截面的依赖性,并给出了QCD修正强烈修正首阶结果的分布。

英文摘要:

We compute the O(alpha_s) QCD corrections to charged triple vector boson production at a hadron collider, i.e. the processes pp -> ZZW + X and pp -> WWW + X. Intermediate Higgs boson exchange effects, spin correlations from leptonic vector boson decays, and off-shell contributions are all taken into account. Results are implemented in a fully flexible Monte Carlo program that allows for an easy customization of kinematical cuts and variation of the factorization and renormalization scales. We analyze the dependence of the differential cross sections under scale variations and present distributions where the QCD corrections strongly modify the leading-order results.
