论文摘要
我们跟进了QCD中三个循环（ARXIV：2001.03008）的希格斯 - 葡聚糖形状的确切夸克质量依赖性的讨论，并将我们的注意力转向密切相关的希格斯 - photon form form。与我们以前的工作类似，我们打算检查QCD中三环水平的Higgs-Boson衰减的外形。由于先前在希格斯 - 葡萄糖外形上的工作，因此以数值为单位而闻名。我们的结果可以用于通过近代到领先的顺序来得出希格斯 - 波森的光子衰减速率。
We follow up on our discussion of the exact quark-mass dependence of the Higgs-gluon form factor at three loops in QCD (arXiv:2001.03008) and turn our attention to the closely related Higgs-photon form factor. Similarly to our previous work, we intend to examine the form factor for the decay of a Higgs-boson with variable mass into two photons at the three-loop level in QCD. The set of master integrals is known numerically due to prior work on the Higgs-gluon form factor and is exploited to obtain expansions around the threshold as well as in the high-energy limit. Our results may be utilised to derive the photonic decay rate of the Higgs-boson through next-to-next-to-leading order.
