Abstract

The branching ratios of the τ- → h- π0vτ and τ- → h- ≥ 2π0vτ decays (where h- is either a π- or K-) are measured using the OPAL detector at LEP. The two branching ratios are simultaneously measured using separate selection criteria and are found to be Bh- π0 = (26.25 ± 0.35 ± 0.52)%, Bh- ≥ 2π0 = (9.89 ± 0.34 ± 0.55)%Bh- π0 + Bh- ≥ 2π0 = (36.14 ± 0.33 ± 0.58)%, where the first error is statistical and the second is systematic.
