Abstract (data abstract)

CERN-LEP. The 132 pb$^{-1}$ of data collected by ALEPH from 1991 to 1994 have been used to analyze $\eta$ and $\omega$ production in $\tau$ decays. The following branching fractions have been measured: $$\begin{eqnarray} B(\tau^-\to\nu_{\tau}\omega h^-) = (1.91 \pm 0.07 \pm 0.06) \times 10^{-2},\\ B(\tau^-\to\nu_{\tau}\omega h^-\pi^0) = (4.3 \pm 0.6 \pm 0.5) \times 10^{-3},\\ B(\tau^-\to\nu_{\tau}\eta K^-) = (2.9^{+1.3}_{-1.2} \pm 0.7) \times 10^{-4},\\ B(\tau^-\to\nu_{\tau}\eta h^-\pi^0) = (1.8 \pm 0.4 \pm 0.2) \times 10^{-3} \end{eqnarray}$$ and the 95% C.L. limit $B(\tau^-\to\nu_{\tau}\eta\pi^-) < 6.2 \times 10^{-4}$ has been obtained. The $\omega\pi^-$ and $\eta\pi^-\pi^0$ rates and dynamics are found in agreement with the predictions made from $e^+e^-$ annihilation data with the help of isospin invariance (CVC). These numbers have been read from the plots in the paper.
