Measurements of charged-particle inclusive distributions in hadronic decays of theZboson

Abstract

We have measured inclusive distributions for charged particles in hadronic decays of the Z boson. The variables chosen for study were charged-particle multiplicity, scaled momentum, and momenta transverse to the sphericity axes. The distributions have been corrected for detector effects and are compared with data from ${\mathit{e}}^{+}$ ${\mathit{e}}^{\mathrm{-}}$ annihilation at lower energies and with the predictions of several QCD-based models. The data are in reasonable agreement with expectations.
