SEARCH FOR HADRONIC EVENTS WITH LOW THRUST AND AN ISOLATED LEPTON WITH THE CELLO DETECTOR

Abstract Using the CELLO detector at the PETRA e + e − -storage ring, a search for hadronic events with low thrust and anisolated lepton has been carried out. The rate of such events and the thrust distribution of inclusive lepton events show no evidence for a threshold of new sources of inclusive lepton events at the highest PETRA energies. The CELLO data thus do not support the observations of the MARK-J and JADE collaborations of an excess of muon events of this type at √ s > 46.3 GeV.
