论文摘要
在弱腐烂和中性介子混合中测量的风味混合和CP违规是测试标准模型（SM）并寻找新物理学的基本工具。在LHC实验上进行的新分析为Cabibbo-Kobayashi-Maskawa（CKM）计量学提供了前所未有的见解，并为罕见衰减提供了新的证据。在几个望子量的理论计算中也取得了重要的进展，并显着减少了不确定性。这种改进是必不可少的，因为先前对单位性三角的研究确实表明，新物理学（如果有的话）可能的贡献必须很小，并且很容易被理论和实验性错误掩盖。得益于实验和理论进步，CKM图片通过全球分析提供了非常精确的SM预测。我们在这里介绍UTFIT协作进行的最新全局SM分析的结果，包括实验，晶格QCD和现象学计算的所有最新输入。
Flavour mixing and CP violation as measured in weak decays and mixing of neutral mesons are a fundamental tool to test the Standard Model (SM) and to search for new physics. New analyses performed at the LHC experiment open an unprecedented insight into the Cabibbo-Kobayashi-Maskawa (CKM) metrology and new evidence for rare decays. Important progress has also been achieved in theoretical calculations of several hadronic quantities with a remarkable reduction of the uncertainties. This improvement is essential since previous studies of the Unitarity Triangle did show that possible contributions from new physics, if any, must be tiny and could easily be hidden by theoretical and experimental errors. Thanks to the experimental and theoretical advances, the CKM picture provides very precise SM predictions through global analyses. We present here the results of the latest global SM analysis performed by the UTfit collaboration including all the most updated inputs from experiments, lattice QCD and phenomenological calculations.
