摘要: 介绍了入射能量约1AGeV时的重离子碰撞产生的介子物理,分析了SIS和Bevalac两个重离子加速器的实验数据中显示的介质效应,特别是手征对称性在有限密度时的部分恢复信号,指出了目前理论研究中存在的问题 ,最后讨论了兰州重离子加速器CSR可以进行的介子物理研究.The meson physics in heavy ion collisions around energy 1 A GeV is investigated. The experimental data at SIS and Bevalac on medium effects, especially on the signatures of chiral symmetry restoration at finite density are analyzed, and the related problems in the study are pointed out. Finally the possible meson physics at cool storage ring (CSR) is discussed.Abstract: The meson physics in heavy ion collisions around energy 1 A GeV is investigated.
