用LEP的OPAL探测器记录的1991-1995年的数据测量了两个衰变的分支比。这些分支比率是使用三个选择标准同时测量的，并且发现\[ \begin{array} {l c c} {\rm BR}(\tau^- \rightarrow h^- \nu_\tau) & = & (11.98 \pm 0.13 \pm 0.16) \%\\ {\rm BR}(\tau^-\rightarrow h^- \pi^0 \nu_\tau) & = & (25.89 \pm 0.17 \pm 0.29) \%\\ {\rm BR}(\tau^- \rightarrow h^- \geq 2 \pi^0 \nu_\tau ) & = & ( 9.91 \pm 0.31 \pm 0.27) \% \end{array} \]，其中第一个错误是统计错误，第二个错误是系统错误。
The branching ratios of theanddecays 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 \[ \begin{array} {l c c} {\rm BR}(\tau^- \rightarrow h^- \nu_\tau) & = & (11.98 \pm 0.13 \pm 0.16) \%\\ {\rm BR}(\tau^-\rightarrow h^- \pi^0 \nu_\tau) & = & (25.89 \pm 0.17 \pm 0.29) \%\\ {\rm BR}(\tau^- \rightarrow h^- \geq 2 \pi^0 \nu_\tau ) & = & ( 9.91 \pm 0.31 \pm 0.27) \% \end{array} \] where the first error is statistical and the second is systematic.
