Description

Latest results from PETRA since autumn last year are presented. New experimental limits on narrow resonances, composite bosons and supersymmetric particles are discussed. A peculiar hadronic event with two isolated muons and high invariant leptonic and hadronic masses is shown. (orig.)

Abstract (German)

Neue Ergebnisse von PETRA seit Herbst letzten Jahres werden vorgestellt. Neue experimentelle Grenzen fuer schmale Resonanzen, zusammengesetzte Bosonen und supersymmetrische Teilchen werden diskutiert. Ein seltsames hadronisches Ereignis mit zwei isolierten Mueonen und grossen invarianten Massen der Leptonen und der Hadronen wird gezeigt. (orig.)
