Current particle phenomenology is characterized by the spectacular agreement of the predictions of the Standard Model of particle physics (SM) with all results from collider experiments and by the absence of significant signals of non-standard physics, despite the fact that we know that the SM cannot be the ultimate theory of nature. In this situation, confronting theory and experiment with high precision is a promising direction to look for potential traces of physics beyond the SM. On the theory side, the calculation of radiative corrections of the strong and electroweak interactions is at the heart of this task, a field that has seen tremendous conceptual and technical progress in the last decades. This review aims at a coherent introduction to the field of electroweak corrections and tries to fill gaps in the literature between standard textbook knowledge and the current state of the art. The SM and the machinery for its perturbative evaluation are reviewed in detail, putting particular emphasis on renormalization, on one-loop techniques, on modern amplitude methods and tools, on the separation of infrared singularities in real-emission corrections, on electroweak issues connected with hadronic initial or final states in collisions, and on the issue of unstable particles in quantum field theory together with corresponding practical solutions.

对撞机物理的弱电辐射校正

当前粒子现象学的特点是粒子物理学标准模型 (SM) 的预测与来自对撞机实验的所有结果惊人一致，并且缺乏非标准物理学的重要信号，尽管我们知道 SM不可能是终极的自然理论。在这种情况下，以高精度面对理论和实验是寻找超越 SM 的潜在物理痕迹的一个有希望的方向。在理论方面，强相互作用和弱电相互作用的辐射校正的计算是这项任务的核心，该领域在过去几十年中取得了巨大的概念和技术进步。本综述旨在对弱电校正领域进行连贯的介绍，并试图填补标准教科书知识与当前最先进技术之间的文献空白。详细回顾了 SM 及其微扰评估机制，特别强调重整化、单环技术、现代振幅方法和工具、实际发射校正中红外奇点的分离、与碰撞中的强子初态或终态，以及量子场论中的不稳定粒子问题以及相应的实际解决方案。
