Abstract

The τ lifetime has been measured with the OPAL detector at LEP, from analyses using the impact parameters in decays to single charged tracks, and the decay lengths from τ decays to three charged tracks. The 1991 sample of approximately 12300 τ-pair events, of which 70% contain silicon microvertex detector information, has been combined with a re-analysis of the 5100 events recorded during 1990. The two statistically-independent determinations give: {Mathematical expression} The weighted average of these results after combination of the uncorrelated systematic errors is: {Mathematical expression}.

N1 - Funding Information: effort of all engineers and technicians of the collaborating institutions in the construction and maintenance of the apparatus, in particular the operation of the magnet system by G. Mayaux and Dr. Horlitz and their groups. The visiting groups wish to thank the DESY directorate for the support and kind hospitality extended to them. This work was partly supported by the Bundesministerium ffir Forschung and Technologie.

N2 - The τ lifetime has been measured with the OPAL detector at LEP, from analyses using the impact parameters in decays to single charged tracks, and the decay lengths from τ decays to three charged tracks. The 1991 sample of approximately 12300 τ-pair events, of which 70% contain silicon microvertex detector information, has been combined with a re-analysis of the 5100 events recorded during 1990. The two statistically-independent determinations give: {Mathematical expression} The weighted average of these results after combination of the uncorrelated systematic errors is: {Mathematical expression}.
