论文摘要
弱玻色子融合中希格斯玻色子的产生是LHC中希格斯生产过程中的第二大横截面。因此，此过程在与载体玻色子的详细研究中起着重要作用。在本文中，我们通过考虑异常的$ hvv $互动和NNLO QCD辐射校正来扩展弱玻色子融合中希格斯玻色子产生的可用描述。我们发现，尽管领先的QCD预测过于不确定，以至于允许对异常耦合进行详细研究，但大多数情况下，NLO QCD结果非常精确。 NNLO QCD校正仅改变了NLO QCD预测，但它们的可用性提高了基于NLO QCD计算的结论的可信度。
The production of Higgs bosons in weak boson fusion has the second largest cross section among Higgs-production processes at the LHC. As such, this process plays an important role in detailed studies of Higgs interactions with vector bosons. In this paper we extend the available description of Higgs boson production in weak boson fusion by considering anomalous $HVV$ interactions and NNLO QCD radiative corrections at the same time. We find that, while leading order QCD predictions are too uncertain to allow for detailed studies of the anomalous couplings, NLO QCD results are sufficiently precise, most of the time. The NNLO QCD corrections alter the NLO QCD predictions only marginally, but their availability enhances the credibility of conclusions based on NLO QCD computations.
