反西格马负超子（Σ-）的发现前后

 因高能加速器建设滞后，中国粒子物理学科在发展早期只能开展理论研究、宇宙线观测或通过国际合作开展高能实验研究。多国合作的杜布纳联合原子核研究所的成立为中国高能物理发展创造了良机，反西格马负超子的发现更是中国物理学史上浓墨重彩的一笔。中国学者在杜布纳的系列科学成就，为此后中国亚原子物理发展奠定了重要的知识基础与人才基础。

Before and after the discovery of anti-sigma negative hyperon

During the early stage of China's particle physics, as the construction of high-energy accelerator lagged behind China could only ‘talk on paper’ in theoretical research, and ‘depend on Heaven for food to eat’ in cosmic ray research or ‘find shelter under other's roof’ in international cooperation. The establishment of the Multinational Joint Nuclear Research Institute in Dubna created a good opportunity for the development of high energy physics in China. The discovery of anti-sigma negative hyperon left a thick and colorful mark in the history of physics in China. The series of scientific achievements by Chinese scholars in Dubna laid an important knowledge and talent foundation for the development of subatomic physics in China.
