Event Selection

The events used in the present analyses were selected from a sample of 2.20 pb collected at a center-of-mass energy of 91.2 GeV in 1992 and 1993. The selection of tau-pair candidates is based on the multiplicity, momentum and direction of tracks in the central drift chamber, and on properties of electromagnetic showers in the calorimeter. Tracks and energy clusters are required to meet certain criteria[8] to be used in the event selection.
