Abstract: In a p+p collision, there are only two leading particles. One is in projectile fragmentation region,the other is in target fragmentation region. The investigation of present paper shows that, just like in nucleus-nucleus collisions, the revised Landau hydrodynamic model alone is not enough to have a good description to the measured pseudorapidity distributions of charged particles in p+p collisions. Only after the leading particles are taken into account as well, can the experimental data be matched up properly. The theoretical model works well in p+p collisions in the whole available energy region from ps=23.6 to 900 GeV.
