| 摘 要： | 在总结双柱模型计算结果的基础上, 用该模型对交变梯度同步加速器(AGS)和相对论性重离子对撞机(RHIC)能区核－核碰撞中的领头粒子效应进行了统一分析. 结果表明:在AGS和RHIC能区, 不同中心性核－核碰撞中带电粒子(赝)快度分布的不同, 主要由领头粒子的贡献影响; 如果扣除领头粒子的贡献, 不同中心性核－核碰撞中带电粒子的(赝)快度分布有相同的形状.

| Abstract: | Based on our previous work, leading particle effects in nucleus-nucleus collisions at the Alternating Gradient Synchrotron (AGS) and Relativistic Heavy Ion Collider (RHIC) energies are uniformly analyzed by using the two-cylinder model. The results show that the differences in the (pseudo)rapidity distributions of the charged particles in nucleus-nucleus collisions with different centralities are mainly affected by the contributions of leading particles. If the contribution of leading particles is neglected, the charged particle (pseudo)rapidity distributions in nucleus-nucleus collisions with different centralities would have the same shape. |
