Multiplicity distribution of final-state particles and different contributions of related sources in nucleus-nucleus collisions at high energies

SUN Zhu1 LIU Fu-Hu2;1 (School of Physics and Electronic Science, Shanxi Datong University, Datong 037009, China) 2 (Institute of Theoretical Physics, Shanxi University, Taiyuan 030006, China)  
The final state particle multiplicity distributions in high-energy nucleus-nucleus collisions are de-scribed by two different sub-distributions contributed by a single nucleon. The Monte Carlo calculated results from the two sub-distributions and the participant-spectator model are compared and found to be in agreement with the experimental data of Au-Au collisions at s~(1/2)=130 AGeV and Pb-Pb collisions at 158 AGeV.
