摘　　要：1974年丁肇中和Richter教授发现粲夸克被称为粒子物理学的革命,随即于1976年荣获诺贝尔奖。研究粲夸克弱衰变性质的粲物理在过去十年间取得巨大进展。首次探测到双粲重子被科技部评为“2017年度中国科学十大进展”,发现粲衰变的电荷-宇称对称性破坏被英国《物理世界》杂志评为“2019年十大突破”。中国理论与实验团队为这两项突破性进展做出了非常重要的贡献。The discovery of charm quark by Prof.Samuel C.C.Ting and Prof.B.Richter in 1974 was a revolution of particle physics,which was quickly awarded by the Nobel Prize in 1976.Charm physics studies the properties of weak decays of charmed hadrons.It had made great progress during the past decade.The discovery of double-charm baryon is awarded as“Top ten progresses of Chinese science in 2017”.The discovery of charge-parity symmetry violation in charm is awarded as“Top ten breakthroughs in 2019”by Physics World.Chinese theorists and experimentalists made significant contributions to them.
