论文摘要
我们探讨了现代散射幅度研究中的各种主题研究如何在对撞机物理过程的描述中找到应用。在对实验测量的数量以及与振幅相关的方式进行了简要审查之后，我们总结了扰动QFT的最新发展，以及它们如何影响我们与围墙进行精确物理学的能力。接下来，我们说明（近代）软辐射的研究与LHC和相关实验的关键过程的理论精度直接相关。最后，我们描述了用于将理论计算变成粒子加速器输出更接近的各种技术。
We explore how various topics in modern scattering amplitudes research find application in the description of collider physics processes. After a brief review of experimentally measured quantities and how they are related to amplitudes, we summarise recent developments in perturbative QFT, and how they have impacted our ability to do precision physics with colliders. Next, we explain how the study of (next-to-)soft radiation is directly relevant to increasing theoretical precision for key processes at the LHC and related experiments. Finally, we describe the various techniques that are used to turn theoretical calculations into something more closely approaching the output of a particle accelerator.
