Hadron calorimetry in the L3 detector

Abstract The characteristics of the L3 hadron calorimeteras realized in the observation of hadronicjets and other events from e + e − collisions at LEP are presented and discussed. The pattern-recognitionalgorithm utilizing the fine granulatiry of the calorimeteris described, and the observed overall resolution of 10.2% for hadronjets from Z decay is reported. The use of the calorimeterin providing information on muon energy losses is also noted.
