Abstract

For many decades, the main source of information on the top-left corner element of the Cabibbo–Kobayashi–Maskawa quark mixing matrix, V ud , was superallowed nuclear β decays with an impressive 0.01% precision. This precision, apart from experimental data, relies on theoretical calculations in which nuclear structure–dependent effects and uncertainties play a prime role. This review is dedicated to a thorough reassessment of all ingredients that enter the extraction of the value of V ud from experimental data. We try to keep balance between historical retrospect and new developments, many of which occurred in just the past 5 years. They have not yet been reviewed in a complete manner, not least because new results are forthcoming. This review aims to fill this gap and offers an in-depth yet accessible summary of all recent developments.

超允许核β衰变与标准模型的精确检验

几十年来，卡比布-小林-马斯卡瓦夸克混合矩阵左上角元素 V ud 的主要信息来源是超允许核 β 衰变，其精度达到了惊人的 0.01%。除了实验数据之外，这一精度还依赖于理论计算，其中核结构效应和不确定性发挥了重要作用。这篇综述致力于彻底重新评估从实验数据中提取 V ud 值的所有因素。我们试图在历史回顾与新发展之间保持平衡，其中许多新发展发生在过去的 5 年中。我们尚未对它们进行全面回顾，尤其是因为新的成果即将问世。本综述旨在填补这一空白，并对所有最新进展进行深入浅出的总结。
