Abstract

We present results obtained from a study of the structure of hadronic events recorded by the L3 detector at a centre-of-mass energy of 183 GeV. The data sample corresponds to an integrated luminosity of 55.3 pb^-1. The distributions of event shape variables and the energy dependence of their mean values are measured. From a comparison with resummed script O sign(α² _s) QCD calculations, we determine the strong coupling constant α_s (183 GeV) = 0.1086 ± 0.0026(exp) ± 0.0054 (th). The charged particle multiplicity distribution and momentum spectrum are studied and the energy dependence of the peak position of the ξ(= - 1n x_p) distribution is compared with lower energy measurements and QCD expectations.

N2 - We present results obtained from a study of the structure of hadronic events recorded by the L3 detector at a centre-of-mass energy of 183 GeV. The data sample corresponds to an integrated luminosity of 55.3 pb-1. The distributions of event shape variables and the energy dependence of their mean values are measured. From a comparison with resummed script O sign(α2 s) QCD calculations, we determine the strong coupling constant αs (183 GeV) = 0.1086 ± 0.0026(exp) ± 0.0054 (th). The charged particle multiplicity distribution and momentum spectrum are studied and the energy dependence of the peak position of the ξ(= - 1n xp) distribution is compared with lower energy measurements and QCD expectations.
