中文摘要：

大型强子对撞机上三规范粒子的伴随产生可以用来检验标准模型中的四线耦合的特性。拟在标准型的理论框架下研究大型强子对撞机（LHC）上W^＋W^-Z的产生过程,计算了该过程的量子色动力学（QCD）的次领头阶（NLO）的修正,给出了这两个过程在不同对撞能量下的截面,分析了这两个过程末态粒子的横动量分布。研究了该过程的半轻子衰变,以及在CMS探测器上的信号。

英文摘要：

Triple gauge boson associated production at the LHC serves as an interesting channel to test the robustness of the Standard Model （ SM）, which can be used to test the quartic coupling characteristics in SM. In this paper, we investigate the production of the W ＋ W - Z process up to QCD NLO in SM at the LHC. We present the dependence of the integrated cross sections on the energy of electron - positron colliding, and various kinematic distributions of final W and Z bosons in the SM. We also investigate the semi - leptonic decay of this process, and the signal on CMS detect.
