我们提出了与大型强子对撞机中的喷气机相关的 W + W − 对的产生的数值结果，其 QCD 处于次领先级 (NLO)。我们将大质量矢量玻色子衰变为具有自旋相关性的轻子的影响以及第三代大质量夸克的贡献包括在内。计算是使用半数值方法进行虚拟校正，并在 MCFM 中实现。除了其本身作为标准模型测试的重要性之外，这个过程还是搜索希格斯玻色子和许多新物理搜索的重要背景。作为一个例子，我们研究了 NLO 修正 W + W − + 射流产生对大型强子对撞机寻找希格斯玻色子的影响。
We present numerical results for the production of a W + W − pair in association with a jet at the LHC in QCD at next-to-leading order (NLO). We include effects of the decay of the massive vector bosons into leptons with spin correlations and contributions from the third generation of massive quarks. The calculation is performed using a semi- numerical method for the virtual corrections, and is implemented in MCFM. In addition to its importance per se as a test of the Standard Model, this process is an important background to searches for the Higgs boson and to many new physics searches. As an example, we study the impact of NLO corrections to W + W − + jet production on the search for a Higgs boson at the LHC.
