title = "Measurement of the τ-→h-h+h-v τ and τ-→h-h+h-≥1π 0vτ branching ratios",
abstract = "The branching ratios of the τ-→h-h+h-v τ and τ-→h-h+h-≥1π 0vτ decays, where h is either a charged π or K meson, are measured using a data sample of 87861 τ+τ- pairs collected with the OPAL detector at LEP. The two branching ratios are extracted simultaneously from a sample of three charged particle decays and found to be: {Mathematical expression} where the first error is statistical and the second systematic. The branching ratio of the τ lepton into three charged particles is measured to be: {Mathematical expression}",
