Particle flow in a jet

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The angular distribution of hadrons in a jet is evaluated in perturbative QCD. The predictions are restrictive in the sense they do no depend on the details of the non-perturbative process. The distribution depends on only one phenomenologically adjustable parameter, a cutoff massQ 0 (in addition to the universal QCD mass-scale Λ). The fit of the leading order prediction to the TASSO data is obtained withQ 0≈270 MeV.The low value ofQ 0 supports the hypothesis of “local partonhadron duality”. The particle flow in a gluon jet is also analysed.
