W+W- + jet: compact analytic results

John Campbell, David Miller, Tania Robens

摘要:

在2015年4月开始的LHC第二次运行中,对标准模型过程的准确理解比以往任何时候都更加重要。包括电弱规范玻色子的过程作为标准烛光用于SM测量,并且同样构成BSM搜索的重要背景。在这里,我们提出了非线性QCD虚拟贡献W+W- +喷流的解析格式通过么正性方法获得,并显示结果的整个过程中使用的实施到蒙特卡洛事件发生器MCFM。唯象,我们调查总以及微分截面的大型强子对撞机与14 TeV的质心能量,以及未来的100 TeV质子质子机。在这里提出的格式中,单圈虚贡献也是计算NNLO的W+W对产生的重要成分。

英文摘要:

In the second run of the LHC, which started in April 2015, an accurate understanding of Standard Model processes is more crucial than ever. Processes including electroweak gauge bosons serve as standard candles for SM measurements, and equally constitute important background for BSM searches. We here present the NLO QCD virtual contributions to W+W- + jet in an analytic format obtained through unitarity methods and show results for the full process using an implementation into the Monte Carlo event generator MCFM. Phenomenologically, we investigate total as well as differential cross sections for the LHC with 14 TeV center-of-mass energy, as well as a future 100 TeV proton-proton machine. In the format presented here, the one-loop virtual contributions also serve as important ingredients in the calculation of W+W- pair production at NNLO.
