MULTIHADRON-EVENT PROPERTIES IN E+E- ANNIHILATION AT SQUARE-ROOT S = 52-57 GEV

We present the general properties of multihadron final states produced by {ital e}{sup +}{ital e}{sup {minus}} annihilation at center-of-mass energies from 52 to 57 GeV in the AMY detector at the KEK collider TRISTAN. Global shape, inclusive charged-particle, and particle-flow distributions are presented. Our measurements are compared with QCD+fragmentation models that use either leading-logarithmic parton-shower evolution or QCD matrix elements at the parton level, and either string or cluster fragmentation for hadronization.
