Forward-Backward Multiplicity Correlations in pp Collisions at 400 GeV/c
- Received Date: 1991-11-14
Abstract: The pseudorapidity distributions of charged particles produced in pp collisions at 400 GeV/c have been measured using LEBC films. The multiplicity distributions in forward hemisphere at fixed total multiplicities are obtained. The forward-backward multiplicity correlation strength in full-phase space, central region, and off-central region of the pseudorapidity distribution are calculated. The correlation strength versus pseudorapidity 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.
