| 英文摘要 | Using data collected with the L3 detector at LEP from 1992 to 1995 on the Z peak, we determine the branching fractions of the tau lepton into one, three and five charged particles to be: B(tau --> (1 -prong)) = 85.274 +/- 0.105 +/- 0.073%, B(tau --> (3-prong)) = 14.556 +/- 0.105 +/- 0.076%, B(tau --> (5-prong)) = 0.170 +/- 0.022 +/- 0.026%. The first uncertainties are statistical and the second systematic. The accuracy of these measurements alone is similar to that of the current world average. (C) 2001 Elsevier Science B.V.
