Description
The angular distribution of hadrons in a jet is evaluated in perturbative QCD. The predictions are restrictive in the sense they do not depend on the details of the non-perturbative process. The distribution depends on only one phenomenologically adjustable parameter, a cutoff mass Q0 (in addition to the universal QCD mass-scale Λ). The fit of the leading order prediction to the TASSO data is obtained with Q0 ≅ 270 MeV. The low value of Q0 supports the hypothesis of 'local parton-hadron duality'. The particle flow in a gluon jet is also analysed. (orig.)
