Abstract
Using τ + τ − pairs in which one τ decays to leptons and the other decays to 3 charged particles we present a high statistics measurement of the τ lepton lifetime. The data used in this analysis were collected with the CLEO detector at CESR and consist of an integrated luminosity of 429 pb −1 taken at, above, and below the ϒ (4S). We use the vertex displacements of the 3 charged tracks to determine the τ lifetime and measure it to be (3.04 ± 0.14 ± 0.07) × 10 −13 s .
