论文摘要
我们介绍了全彩色无质量QCD中三环四粒子螺旋幅度的计算方面的最新进展。在此贡献中，我们专注于$ gg \至γγ$过程。我们展示了如何获得三环散射幅度的紧凑分析公式。我们的结果可以用谐波多组载体表示，从而可以进行有效的数值评估。此处介绍的结果可用于改善与HADRON COLLIDERS上HIGGS物理相关的理论预测。
We present recent advancements in the computation of three-loop four-particle helicity amplitudes in full-color massless QCD. In this contribution, we focus on the $gg \to γγ$ process. We show how to obtain compact analytic formulae for the three-loop scattering amplitude. Our results can be expressed in terms of harmonic polylogarithms, which allows for an efficient numerical evaluation. The results presented here can be used for improving theoretical predictions relevant for Higgs physics at hadron colliders.
