我们回顾了粲夸克领域中味改变中性流的现状。我们聚焦于标准模型的预测，并确定了在混合和罕见粲夸克衰变中理论不确定性的主要来源。这些可观测量在约束标准模型及其扩展中的短程物理方面的潜力，因大量非微扰效应的存在而受到影响。我们研究了可以测试短程物理的可能的发现窗口，并研究了标准模型各种扩展的影响。还回顾了当前的实验状况和未来前景。
We review the current status of flavor-changing neutral currents in the charm sector. We focus on the standard-model predictions and identify the main sources of theoretical uncertainties in both mixing and rare charm decays. The potential of these observables for constraining short-distance physics in the standard model and its extensions is compromised by the presence of large nonperturbative effects. We examine the possible discovery windows in which short-distance physics can be tested and study the effects of various extensions to the standard model. The current experimental situation and future prospects are reviewed.
