LHC上WW + 1喷流分布的次领先阶预测

Next-to-leading order predictions for WW + 1 jet distributions at the LHC

John M. Campbell, R. Keith Ellis, G. Zanderighi

摘要:

我们给出了在次领先阶(NLO)QCD中LHC中与喷流相关的$W^+W^-$对产生的数值结果。我们包括了大量的矢量玻色子衰变成轻子的自旋相关和贡献的第三代大质量夸克的影响。计算使用半数值方法的虚拟修正,并在MCFM中实现。除了它作为标准模型测试的重要性{ \it本身},这个过程是寻找希格斯玻色子和许多新物理学研究的重要背景。作为一个例子,我们研究的影响,非线性光学修正$W^+W^-+$喷流生产上寻找一个希格斯玻色子在大型强子对撞机。

英文摘要:

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 {\it 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.
