Abstract：
The pseudorapidity distributions of charged particles produced in pp collisions at 400 GeV/c have been measured by using the LEBC films offered by the CERN NA27 Collaboration. The scaled factorial cumulant moments have been calculated. Compared with the results obtained from Monte Carlo events with the same single-particle spectrum and no correlations, a significant part of K₂ for broad mixed multiplicity distributions comes from single-particle density fluctuation owing to the fluctuating multiplicity. The factorial cumulant moments obtained by using the star correlation integrals reduce significantly the statistical errors of the higher order cumulant moments, but the essential conclusions remain unchanged.
