A MEASUREMENT OF THE TAU-LIFETIME
- 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, G τ/G μ=0.967±0.040 consistent with the concept of lepton universality. © 1988 Springer-Verlag.
