Measurement of the one-prong hadronic $\tau$ branching ratios at LEP

The branching ratios of the \tau^- -> h^- \nu_\tau, \tau^- -> h^- \pi^0 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 BR(\tau^- -> h^- \nu_\tau) = (11.98 +/- 0.13 +/- 0.16)% BR(\ta...

Sumario:The branching ratios of the \tau^- -> h^- \nu_\tau, \tau^- -> h^- \pi^0 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 BR(\tau^- -> h^- \nu_\tau) = (11.98 +/- 0.13 +/- 0.16)% BR(\tau^- -> h^- \pi^0 \nu_\tau) = (25.89 +/- 0.17 +/- 0.29)% BR(\tau^- -> h^- >=2 \pi^0 \nu_\tau) = ( 9.91 +/- 0.31 +/- 0.27)% where the first error is statistical and the second is systematic.
