论文摘要
$β$衰减中初始粒子和最终粒子之间的角相关性的测量仍然是探测标准模型并寻找新物理学的最有希望的方法之一。随着实验在人均方面达到了前所未有的精度，正确提取结果需要考虑到一项过程中的大量核结构和辐射校正，这将取决于实验几何形状。我们在这里提供了理论结果的汇编和更新，这些结果描述了同一概念框架中的所有校正，指出陷阱并回顾实验几何的影响。最后，我们总结了新物理学的潜力。
Measurements of angular correlations between initial and final particles in $β$ decay remain one of the most promising ways of probing the Standard Model and looking for new physics. As experiments reach unprecedented precision well into the per-mille regime, proper extraction of results requires one to take into account a great number of nuclear structure and radiative corrections in a procedure which becomes dependent upon the experimental geometry. We provide here a compilation and update of theoretical results which describe all corrections in the same conceptual framework, point out pitfalls and review the influence of the experimental geometry. Finally, we summarize the potential for new physics reach.
