Abstract
Charged-particle multiplicity distributions from hadron-hadron collisions at {Mathematical expression}=16.7 GeV are analyzed in rapidity, pseudorapidity and azimuthal angle intervals. The data-fully reconstructed events-were taken in the rapid-cycling Bubble Chamber of the International Hybrid Spectrometer Consortium exposed to a hadron beam (147 GeV/c momentum) of the Tevatron at Fermilab. The factorial moments of the multiplicity distributions increase with decreasing rapidity interval. The energy dependence of the slopes in h-h collisions is discussed. Suitable phase-space cuts show that most of the intermittency effect stems from low-transverse-momentum particles. In the two-dimensional analysis (rapidity azimuthal angle) we find a weak enhancement of the slope values, more in agreement with the observations by the NA22 experiment, rather than the observations in e+e- by the HRS collaboration.
