A measurement of the τ lifetime
European Physical Journal C 39:3 (2005) 331-337
Abstract:
We have reconstructed 695 three-track τ decay vertices using a high resolution drift chamber close to the interaction point. From the distribution of decay lengths we measure the lifetime to be (3.06 ±0.20±0.14)×10-13 s. Using this result we find that the ratio of charged weak coupling constant for the τ to that of the μ, GDetector concepts
