摘要: 自J/ψ粒子和τ轻子在20世纪70年代被发现后,τ-粲物理研究即蓬勃兴起,多个正负电子对撞机在此能量运行,取得了丰硕的成果.文章简要论述了国内外长期进行τ-粲物理研究的原因,介绍了其研究的主要内容与特点,并结合新近完成的北京正负电子对撞机重大改造工程(BEPCⅡ)及北京谱仪(BESⅢ),举例介绍了BESⅢ在轻强子谱、粲物理、粲偶素物理研究,量子色动力学及强子产生性质研究和τ-轻子物理研究方面的主要科学目标、任务及新近取得的主要成果.Abstract: Since the discovery of J/ψ and the τ lepton in 70's, the very active: several dedicated e+ e- colliders were built and tremendous per, the main reasoning, the content and the characteristics of the r study of τ-charm physics became progress were obtained. In this pacharm physics study are discussed, together with the scientific motivations and the latest results of the recently completed upgrade of the Beijing Electron--Positron Collider(BEPC Ⅱ ) and the new Beijing Spectrometer(BESⅢ).
