Abstract：
The pseudo-rapidity distributions of charged particles produced in pp collisions at 400GeV/c have been measured using LEBC films.The multiplicity distributions in forward hemis-phere at fixed total multiplicities are obtained.The forward-backward multiplicity correlation strength in full phase spsce,central region and off-central region of the pseudo-rapidity distribution are calculated.
The figures of the correlation strength versus pseudo-rapidity windows are obtained.The experimental data of the forward-backward correlation have been analyzed with cluster model.The results show that the average cluster size is dependent on whether the leading-particle effect is taken into account.
