摘要: 用多源理想气体模型和三火球模型分析并计算了能量在40, 80, 158 AGeV下中心PbPb碰撞中所产生的Λ和强子的横质量分布和快度分布, 发现模型计算的结果与NA49合作组的实验结果相一致。The transverse mass and rapidity distributions of Lambda and Antilambda hyperons produced in central PbPb collisions at 40, 80, and 158 AGeV are described by the multisource ideal gas model and the threefireball model. The results calculated by the models are compared and found to be in agreement with the experimental data of the NA49 Collaboration.Abstract: The transverse mass and rapidity distributions of Lambda and Antilambda hyperons produced in central PbPb collisions at 40, 80, and 158 AGeV are described by the multisource ideal gas model and the threefireball model.
