标题： Mixing and $CP$ violation in the charm system

摘要： 近年来，魅物理经历了一场复兴，这一复兴是由$B$-factories、Tevatron 和 LHCb 的意外且令人印象深刻的实验结果所推动的。$D^0\bar{D}{}^0$振荡的存在现在已经得到充分确立，最近在$D^0$衰变中发现的$CP$破坏进一步激发了对魅区的兴趣。在本文中，我们回顾了当前魅混合和$CP$破坏测量的状况，并评估它们与标准模型及之外的理论预测的一致性。我们期待在未来二十年内实验精度的巨大改进，以及理论理解相应进步的前景。 显示英文摘要

摘要： In recent years charm physics has undergone a renaissance, one which has been catalysed by an unexpected and impressive set of experimental results from the $B$-factories, the Tevatron and LHCb. The existence of $D^0\bar{D}{}^0$ oscillations is now well established, and the recent discovery of $CP$ violation in $D^0$ decays has further renewed interest in the charm sector. In this article we review the current status of charm-mixing and $CP$-violation measurements, and assess their agreement with theoretical predictions within the Standard Model and beyond. We look forward to the great improvements in experimental precision that can be expected over the coming two decades, and the prospects for corresponding advances in theoretical understanding.
