Abstract

The branching ratios of the τ−→h−νττ−→h−ντ τ−→h−π0νττ−→h−π0ντ and τ−→h−≥2π0νττ−→h−≥2π0ντ decays have been measured using the 1991–1995 data recorded with the OPAL detector at LEP. These branching ratios are measured simultaneously using three selection criteria and are found to be where the first error is statistical and the second is systematic.
