| 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. |
