Abstract
An analysis of the properties of hadronic final states produced in ele ctron-positron annihilation at centre-of-mass energies of 130 and 136 GeV is presented. The measurements are based on a data sample of 5.7 p b(-1) collected in November 1995 with the ALEPH detector at LEP. Inclu sive charged particle distributions, jet rates and event-shape distrib utions are measured and the results are compared with the predictions of QCD-based models. From the measured distributions quantities are de termined for which the dependence on the centre-of-mass energy can be predicted by QCD, including the mean multiplicity of charged particles , the peak position of the inclusive distribution of xi = - 1nx(p) (x( p) = p/p(beam)), and the strong coupling constant alpha(s). The QCD pr edictions are tested by comparing with corresponding measurements at E (cm) = 91.2 GeV and at lower energies.
