Description

The performances of the H1 liquid argon calorimeter modules for the energy measurements and identification of electrons are studied with test data taken at CERN in the energy range 5 to 166 GEV. Various electron identification estimators exploiting global or detailed shower characteristics are studied and compared. The usage of impact position measurements is also discussed. A best combination of robust shower estimators leads typically to π-misidentification prohabilities in the range 1.5 to 5.0x10-3 at 30 GeV for 95% electron detection efficiency. This further reduces to ∼10-4 for these pions to be misidentified as electrons below 25 GeV. (orig.)
