Description

From an analysis of data taken with the detector PLUTO at the DORIS storage rings we have obtained evidence for jet structure in e+e- annihilation with hadrons. Results for mean sphericity, mean thrust, the angular dependence of the jet axis and for and with respect to the jet axis are presented. At 9.4 GeV we also discuss the angular dependence of the charged and neutral deposited energy with respect to the jet axis. (orig.) 891 WL

Abstract (German)

Aus einer Analyse von Daten, die mit dem PLUTO-Detektor am DORIS-Speicherring gewonnen wurden, konnten Hinweise auf eine Jet-Struktur der e+e- -Vernichtung in Hadronen gefunden werden. Fuer die mittlere Sphaerizitaet, den mittleren Schub, die Winkelabhaengigkeit der Jet-Achse und fuer und relativ zur Jet-Achse werden Ergebnisse angegeben. Daneben wird die Winkelabhaengigkeit bezueglich der Jet-Achse der bei 9,4 GeV in geladenen und neutralen Teilchen abgegebenen Energie diskutiert. (orig.)
