Factorial and cumulant moments in e{sup +}e{sup {minus}} {yields} hadrons at the Z{sup 0} resonance

Description

The ratio of cumulant to factorial moments of the charged particle multiplicity distribution in hadronic Z{sup 0} decays has been measured in the SLD experiment at SLAC. The data were corrected for effects introduced by the detector. We find that this ratio, as a function of the moment rank q, decreases sharply to a negative minimum at q{approx}5, followed by a sequence of quasi-oscillations. We show that the truncation of the tail of the multiplicity distribution due to finite statistics only has a small effect on this result. The observed features are in qualitative agreement with expectations from higher order ... continued below
