论文摘要
我们将光子Quark和Higgs-Gluon形式计算为无质量扰动量子染色体动力学中的四环阶。我们的结果构成了n $ {}^4 $ lo cross部分的现成构建块，用于DRELL-YAN工艺和LHC的Gluon-Fusion Higgs Boson生产。我们介绍了这两个形式的完整分析表达式，并显示了几个最复杂的主积分。
We compute the photon-quark and Higgs-gluon form factors to four-loop order within massless perturbative Quantum Chromodynamics. Our results constitute ready-to-use building blocks for N${}^4$LO cross sections for Drell-Yan processes and gluon-fusion Higgs boson production at the LHC. We present complete analytic expressions for both form factors and show several of the most complicated master integrals.
