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.
