Abstract

I describe the history of the calculations of NLO and NNLO QCD corrections to weak decays of mesons, particle–antiparticle mixing and electric dipole moments (EDMs) in the period 1988–2023. Also existing calculations of electroweak and QED corrections to these processes are included in this presentation. These efforts bear some analogies to the climbing of Himalayas and various expeditions by several teams of strongly motivated “climbers” allowed to move this field from the LO through the NLO to the NNLO level. We also summarize the most recent calculations within the Standard Model Effective Field Theory. The material is meant to be an up to date review of this very advanced field in non-technical terms as much as possible and a guide to the rich literature on NLO and NNLO corrections in question. In particular we stress for which processes these calculations are crucial for the tests of the Standard Model and to be able to differentiate between numerous New Physics models. It includes also several anecdotes related to the climbs that I was involved in. I hope that some of the comments made in the course of the presentation could turn out to be not only amusing but also instructive.

NLO和NNLO弱衰减峰的攀登:1988-2023

本文描述了1988-2023年间NLO和NNLO QCD对介子弱衰变、粒子-反粒子混合和电偶极矩(edm)的修正计算历史。此外，这些过程的电弱和QED修正的现有计算也包括在本报告中。这些努力与攀登喜马拉雅山脉和几支动机强烈的“登山者”团队的各种探险有一些相似之处，这些探险队被允许将这个领域从LO通过NLO移动到NNLO水平。我们还总结了标准模型有效场论的最新计算。该材料旨在尽可能以非技术术语对这一非常先进的领域进行最新的回顾，并指导有关NLO和NNLO校正的丰富文献。我们特别强调，这些计算对于标准模型的测试和区分众多新物理模型至关重要。它还包括一些与我参与的攀登有关的轶事。我希望大家在演讲过程中提出的一些意见不仅有趣，而且有益。

期刊介绍： Physics Reports keeps the active physicist up-to-date on developments in a wide range of topics by publishing timely reviews which are more extensive than just literature surveys but normally less than a full monograph. Each report deals with one specific subject and is generally published in a separate volume. These reviews are specialist in nature but contain enough introductory material to make the main points intelligible to a non-specialist. The reader will not only be able to distinguish important developments and trends in physics but will also find a sufficient number of references to the original literature.
