论文摘要
我们通过在五燃烧方案中的QCD扰动理论中融合了两个底部夸克，以融合了两个底部夸克，以呈现出Higgs Boson的党横截面的分析结果。我们将这种扰动的结果与四风灯方案中的NLO准确预测相结合，其中包括完整的底部夸克质量依赖性，通过适当地删除来自两个预测中包含的贡献的任何双重计数。因此，我们可以通过强子墙面的底部夸克融合来获得Higgs玻色子的包含生产概率的最新预测。
We present analytic results for the partonic cross sections for the production of a Higgs boson via the fusion of two bottom quarks at N$^3$LO in QCD perturbation theory in the five-flavour scheme. We combine this perturbative result with NLO accurate predictions in the four-flavour scheme that include the full bottom quark mass dependence by appropriately removing any double-counting stemming from contributions included in both predictions. We thereby obtain state-of-the-art predictions for the inclusive production probability of a Higgs boson via bottom quark fusion at hadron colliders.
