Recently, the LHCb collaboration observed the CP violation in charm decays for the first time, in the Cabibbo-suppressed processes of D0->K+K- and pi+pi-. The observed value of CPV is consistent with the theoretical prediction in 2012. We will interpret it in the Standard Model and its implications in the future measurements at Belle II and LHCb. In addition, we find a new CP-violation effect in the Cabibbo-favored charm decays into neutral kaons, induced by the interference between mother decay and daughter mixing. It is large enough to be accessible at the LHCb and Belle II experiments. 于福升，2008年至2013年就读于中国科学院高能物理研究所并获理学博士学位，2011至2012年在巴黎第十一大学作联合培养博士生，2013年至今为兰州大学核科学与技术学院副教授、教授。从事粒子物理理论方面的研究工作，包括重味物理相关的唯象学、精确检验标准模型和寻找超出标准模型的新物理。指出了寻找双重味重子的最佳探测过程，建议和引导LHCb实验首次探测到双粲重子。到目前在Phys.Rev.Lett, Phys.Rev.D, JHEP, Eur.Phy.J.C等国际主流期刊发表二十余篇学术论文。
