论文摘要
LHC实验将实现流程的百分比精度测量值，这是当代粒子物理学最紧迫的问题的关键：Higgs Boson的性质是什么？我们可以成功地描述高能量下基本颗粒的相互作用吗？ LHC上的标准模型外是否有物理学？在QCD扰动理论中，在近代到接头到领先顺序（n $^3 $ lo）上预测和描述此类可观察到的能力对于充分利用这些实验测量至关重要。我们描述了N $^3 $ LO预测的当前状态，并在LHC的即将到来的精确阶段中强调了它们的重要性。此外，我们确定了必要的关键概念和数学发展，以了解广泛的n $^3 $ lo现象学实现。
The LHC experiments will achieve percent level precision measurements of processes key to some of the most pressing questions of contemporary particle physics: What is the nature of the Higgs boson? Can we successfully describe the interaction of fundamental particles at high energies? Is there physics beyond the Standard Model at the LHC? The capability to predict and describe such observables at next-to-next-to-next-to-leading order (N$^3$LO) in QCD perturbation theory is paramount to fully exploit these experimental measurements. We describe the current status of N$^3$LO predictions and highlight their importance in the upcoming precision phase of the LHC. Furthermore, we identify key conceptual and mathematical developments necessary to see wide-spread N$^3$LO phenomenology come to fruition.
