| Abstract: | The pseudorapidity distribution function of charged particles in nucleon nucleon collisions was presented. By using Glauber model, the mean numbers of participants, spectators in collision area, leading particles and binary nucleon nucleon collisions were calculated. The pseudorapidity distributions of charged particles in nucleus nucleus collisions are obtained. The theoretical results are consistent with those of the experimental observations in Au Au collisions at sNN=130 GeV made by the PHOBOS collaboration. |
