| 摘 要： | 报道了用不依赖于任何物理模型的纯数理统计的方法对EMU01实验组200A GeV的32S与固定的Au靶碰撞中较高多重数和较大起伏事例的数据和STAR实验组在核-核质量中心能量为sqrt{s_{_{rm NN}}}=200GeV的Au+Au碰撞中较高多重数和较大起伏事例的数据所做的分析. 对3个相差很远的能区——固定靶加速器能区, 核-核对撞机能区以及宇宙线能区所得的分析结果进行了比较, 并对所得的结果进行了讨论.

| Abstract: | High-multiplicity and large-fluctuation data for nucleus-nucleus collision processes at different energy-ranges are analyzed in an event-by-event manner, by using model-independent statistical methods. The result of the analyses obtained by using CERN-EMU01(32S on fixed Au target at 200AGeV) data and that obtained by using RHIC-STAR(Au Au at (SNN)/(1/2) = 200GeV) data are compared with each other; they are also compared with the existing result obtained by using JACEE-data at cosmic-ray energies. The results of such comparison are presented and discussed. |
