Abstract

The mean charged multiplicity as well as its distribution has been measured as a function of c.m. energy in the reaction e⁺e^-→hadrons. Fragmentation models are compared with the data. After applying radiative corrections the mean charged multiplicity is measured to be 8.4±0.3±0.6 at 12 GeV, 13.1±0.3±0.6 at 30 GeV and 13.6±0.3±0.6 at 35 GeV. The ratio of mean charged multiplicity to the dispersion (<N_ch>/D_ch) is almost constant in the energy range studied, indicating KNO scaling of the charged multiplicity. The inclusive differential cross section s(dσ/dx_p) shows scaling violation in the high x_p region (x_p>0.15). The absolute value of the scaling violation is consistent with the result of 2nd order QCD calculations. The production of neutral kaons has been investigated by identifying the decay K_S ⁰→π⁺π^-. The production probability for a strange quark relative to that of a u or d quark in the fragmentation, γ_s, has been determined to be 0.27±0.03±0.05 averaged over c.m. energies from 12 to 35 GeV. Momentum spectra for neutral kaons are presented and are compared with model predictions.
