چکیده
We measure the T lepton lifetime with r+rpairs in which one or both of the T’S decays to three charged particles. The data were. collected with the CLEO II detector operating at the electron-positron collider CESR at energies on and near the Y(4.T). We use displacements of the three-track vertices to determine the 7 lifetime. The result is r7 = 289.0f 2.8 f 4.0 fs. PACS: 13.1O.+q; 13.35.+s

Measurement of the Tau Lifetime at Sld
A measurement of the lifetime of the tau lepton has been made using a sample of 1671 Z 0 ! + , decays collected by the SLD detector at SLC. The measurement beneets from the small and stable collision region at SLC and the precision pixel vertex detector of SLD. Three analysis techniques have been used: decay length, impact parameter, and impact parameter diierence methods. The combined result i...
متن کاملPrecise measurement of the lifetime of the tau lepton.
Data accumulated with a high-precision vertex drift chamber operating in the PEP detector MAC are used for a precise measurement of the lifetime of the T lepton. Results from a decay-length analysis of a sample in which one T decays into one charged particle and the other to three charged particles are combined with those from an impact-parameter analysis of an independent sample of events that...

We report an update to our previous measurement of the CKM element |Vub| using exclusive B → π`ν decays. In the charm sector we have performed a measurement of fDs using D + s → τ ντ decays, we have measured the mixing parameter yCP using the lifetime ratio 〈τKπ〉 〈τhh〉 in D decays, and we have also searched for CP violation using T-odd correlations in D decays to K+K−π+π−. Finally, in the tau s...
