我们认为电弱Higgs加上三喷生产在NLO QCD超出严格的VBF接受削减。我们调查，第一次，如何准确的VBF近似是在这些地区和微扰的不确定性，详细比较完整的和近似的计算。我们发现，标记射流之间的快度间隙保证了一个很好的近似，而不变的质量切割是不够的，这需要面对实验的选择。我们还发现，一个显着的一部分QCD修正可以归因于希格斯-Strahlungs型拓扑结构。
We consider electroweak Higgs plus three jets production at NLO QCD beyond strict VBF acceptance cuts. We investigate, for the first time, how accurate the VBF approximation is in these regions and within perturbative uncertainties by a detailed comparison of full and approximate calculations. We find that a rapidity gap between the tagging jets guarantees a good approximation, while an invariant mass cut alone is not sufficient, which needs to be confronted with experimental choices. We also find that a significant part of the QCD corrections can be attributed to Higgs-Strahlungs-type topologies.
