高能Pb-Pb中心碰撞中产生的Λ和强子的横质量分布和快度分布(英文)

Transverse Mass and Rapidity Distributions of Λ and Hyperons Produced in Central Pb-Pb Collisions

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 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.
