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Pb-Pb碰撞中所产生的(A)和(A)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.Abstract: The transverse mass and rapidity distributions of Lambda and Antilambda hyperons produced in central Pb-Pb collisions at 40,80,and 158 AGeV are described by the multisource ideal gas model and the three-fireball model.The results calculated by the models are compared and found to be in agreement with the experimental data of the NA49 Collaboration.
