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

Abstract The database system developed for the L3 experiment at the CERN large electron-positron (LEP) collider is described. The solution chosen has two components: a FORTRAN package (DBL3) and a system of distributed servers and data (L3DBSM). DBL3 provides basic database functions supplemented by facilities specific to high-energy physics experiments. The L3DBSM system, operational since the start of LEP data taking, has handled efficiently several hundred Mbytes of data over three different systems (VAX/VMS, IBM VM/CMS, Apollo Aegis SR10.x) and at eight different sites.

Abstract A neural network is constructed to identify the decays τ → ρν in the L3 detector at LEP. The same network is used to identify τ → π (K) ν and τ → e ν ν as a cross check. High efficiency in the rho channel is obtained. A major effort has been made to study the systematic errors introduced by the use of a neural network and no obvious bias has been found.

Abstract A brass tube prototype calorimeter for the L3 detector has been exposed to the X3 beam of the CERN SPS. Its performance, tested with muons and electrons, is very satisfactory. With a sampling of 14 mm of copper, the energy resolution is 30% for 4 GeV pions.
