论文摘要
在这些讲义中，审查了QED校正的基础知识，以特别强调概念（例如，对红外敏感日志的计数和跟踪），而不是数值方面。对于增加复杂性和降低的包容性的情况，说明了一般事务：$ e^+ e^ - \ to Hadrons $，Leptonic Decay $π^+ \ to \ ell^+ \ barν$和半衰减的衰减$ b \ toπ\ ell^+ el^+ bar c n $。非常简短地概述了包括结构依赖的非平凡和持续的努力。
In these lecture notes the basics of QED corrections to hadronic decays are reviewed with special emphasis on conceptual (e.g. counting and tracking of infrared sensitive logs) rather than numerical aspects. General matters are illustrated for the cases of increased complexity and decreased inclusiveness: $e^+ e^- \to hadrons$, the leptonic decay $π^+ \to \ell^+ \bar ν$ and the semileptonic decay $B \to π\ell^+ \bar ν$. The non-trivial and ongoing efforts of including structure dependence are very briefly outlined.
