摘要:

我们提出了精确的预测希格斯玻色子生产与喷流。我们的计算精确到Higgs有效场论中的次次领头阶(NNLO)QCD,并首次对强子碰撞中末态喷注产生Higgs进行了完整的NNLO计算.我们包括所有相关的唯象通道和目前的全差分结果,以及总截面的大型强子对撞机。与NLO QCD预测相比,我们的NNLO预测将非物理尺度依赖性降低了两倍以上,并将总速率提高了约20%。我们的结果表明,第一次令人满意的收敛性的摄动级数。

英文摘要:

We present precise predictions for Higgs boson production in association with a jet. Our calculation is accurate to next-to-next-to-leading order (NNLO) QCD in the Higgs Effective Field Theory and constitutes the first complete NNLO computation for Higgs production with a final-state jet in hadronic collisions. We include all relevant phenomenological channels and present fully-differential results as well as total cross sections for the LHC. Our NNLO predictions reduce the unphysical scale dependence by more than a factor of two and enhance the total rate by about twenty percent compared to NLO QCD predictions. Our results demonstrate for the first time satisfactory convergence of the perturbative series.
