Description
From the hypothesis that the characteristics of hadronic production in e+e- are those seen in transverse distributions of hadron-hadron collisions we are lead to consider the inclusive distributions in e+e- annihilation as composed of two contributions, a cluster component which contains the e+e- resonances, and a parton component. The decay of the cluster is described by the same production radii as those observed in hadron-hadron collisions. The parton component obeys asymptotically Bjorken scaling, and the approach to scaling is set by a mass of 1.2 GeV. Within this picture we give a simple explanation of the energy dependence of the average charged energy and the multiplicity. (orig.)

Von der Hypothese, dass die Merkmale der Hadronenbildung in e+e- den Merkmalen von Transversalverteilungen von Hadron-Hadron-Stoessen entsprechen, gelangt man zu der Annahme, dass die Inklusivverteilungen bei der e+e--Vernichtung aus zwei Beitraegen bestehen: einer Clusterkomponente, die die e+e--Resonanzen enthaelt, und einer Partonkomponente. Der Zerfall des Clusters wird mit den bei Hadron-Hadron-Stoessen beobachteten Erzeugungsradien beschrieben. Die Partonkomponente folgt dem asymptotischen Bjorken-Massstab, der mit einer Masse von 1,2 GeV festgelegt ist. Im Rahmen dieses Modells wird eine einfache Erklaerung fuer die Energieabhaengigkeit der mittleren Energie geladener Teilchen und der Multiplizitaet gegeben. (orig./AK)
