论文摘要
本文调查了Cabibbo-Kobayashi-Maskawa矩阵的一级测试所附的重要问题，重点是直接确定CKM矩阵元素的大小。讨论了当前的CKM异常，并设想了LHCB和Belle II的清晰前景。从$ c \！p $ - 支持和$ c \！p $ - 在LHCB和Belle〜ii实验预计的升级中可观察到的可观察物的预期，从搜索$ b $ -Meson混合中的新物理学的角度来研究，以对瓶颈进行实验，并在限制的实验中进行实验，并将其用于未来的实验。挑战。最终讨论了以$ z^0 $ pole和$ w^+w^ - $运行的未来$ e^+e^ - $ collider的充满活力的潜在客户。
This article surveys the important questions attached to unitarity tests of the Cabibbo-Kobayashi-Maskawa matrix, with a focus on the direct determinations of the magnitude of CKM matrix elements. The current CKM anomalies are discussed and the clear-cut prospects at LHCb and Belle II envisaged. The anticipated precision on $C\!P$-conserving and $C\!P$-violating observables at the projected upgrades of the LHCb and Belle~II experiments is examined from the point of view of the search for New Physics in $B$-meson mixing, addressing the bottlenecks in precision for the interpretation of the measurements for future experiments and highlighting the related theoretical and experimental challenges. The vibrant prospects at future $e^+e^-$ colliders running at the $Z^0$ pole and $W^+W^-$ are eventually discussed.
