Jet structure and scaling in e+e- annihilation

An uncorrelated jet model, with randomly oriented jet axis and parameters as determined from high-energy hadronic interactions is applied to e+e-annihilation. The resulting features (multiplicities, spectra, correlations, branching ratios) are calculated both at finite c.m.s. energies [(3-5)GeV] and asymptotically, in order to study the approach to asymptotic behaviour expected for quark, parton and similar models. It is shown that such description, when the jet structure is the same as in hadron-hadron interactions, lead for kinematic reasons to very late scaling of the normalized inclusive hadron distribution. Results are compared with cluster models for e+e- annihilation and with data
