Abstract

We report a new and precise measurement of the lifetime of the 𝜏 lepton. The data were taken with the High Resolution Spectrometer at the SLAC 𝑒+⁢𝑒− colliding-beam facility PEP operating at 29 GeV center-of-mass energy. The flight distances of 1311 𝜏 decays to three charged particles were measured with a four-layer tubular-cell vertex chamber in conjunction with the main drift chamber. The resulting lifetime of the 𝜏 lepton is 𝜏𝜏=(2.99±0.15±0.1⁢0)×10−13 sec.
