The performance of lead tungstate crystals using photomultipliers and Si avalanche photodiodes to detect the scintillation light has been studied using high energy electron, pion and muon beams at...

Measurement of the lifetime of the $\tau$ lepton (1996)

Acciarri, M., Adriani, O., Aguilar-Benitez, M., Ahlen, S., Alpat, B., Alcaraz, J., ...

The lifetime of the tau lepton is measured using data collected in 1994 by the L3 detector at LEP. The precise track position information of the Silicon Microvertex Detector is exploited. The tau...
