CUMULANT TO FACTORIAL MOMENT RATIO OF MULTIPLICITY DISTRIBUTIONS OF PP INTERACTIONS AT 400 GEV C/

The ratios H-q of the cumulant to a factorial moment of multiplicity d istributions in different pseudorapidity intervals have been calculate d by using the experimental data of multiplicity production for pp col lisions at 400 GeV/c. As a function of the rank, a rapid descent and t hen an oscillation around zero have been observed. In contrast with th e PQCD prediction, the position of the first minimum moves to higher r ank for a smaller interval.
