Charged-particle multiplicities in e sup + e sup minus annihilations at radical s =50--61. 4 GeV

We present the charged-particle multiplicity distributions for {ital e}{sup +}{ital e}{sup {minus}} annihilation at center-of-mass energies from 50 to 61.4 GeV. The results are based on a data sample corresponding to a total integrated luminosity of 30 pb{sup {minus}1} obtained with the AMY detector at the KEK storage ring TRISTAN. The charged-particle multiplicity distributions deviate significantly from the modified Poisson and pair Poisson distributions, but follow Koba-Nielsen-Olesen scaling and are well reproduced by the LUND parton-shower model.
