ResumoCumulant moments of negatively charged and charged particles observed in ${\mathit{e}}^{+}$${\mathit{e}}^{\mathrm{\ensuremath{-}}}$ collisions are analyzed by the modified negative binomial distribution (MNBD). The cumulant moment of observed negatively charged particles shows an oscillatory behavior more regularly than that of the charged particles as the rank of the moment increases. Those behaviors are well described by the MNBD. The characteristics of the MNBD are discussed comparing them with those of the negative binomial distribution. \textcopyright{} 1996 The American Physical Society.
