Topologische Verzweigungsverhltnisse des $\tau$-Leptons bei ALEPH
The inclusive production of the omega(782) vector meson in hadronic Z decays is studied and compared to model predictions. The analysis is based on 1,005,535 hadronic Z decays recorded by the ALEPH detector in the 1992 and 1993 running periods of LEP. Decays of the omega -> pi^+ pi^- pi^0 are rec...

| description | The inclusive production of the omega(782) vector meson in hadronic Z decays is studied and compared to model predictions. The analysis is based on 1,005,535 hadronic Z decays recorded by the ALEPH detector in the 1992 and 1993 running periods of LEP. Decays of the omega -> pi^+ pi^- pi^0 are reconstructed for x_p > 0.05, where x_p = p/p_{beam}. For this momentum range the omega production rate is measured to be 0.633 +- 0.025(stat) +- 0.056(sys) per event. An extrapolation to x_p = 0 yields a total production rate of 1.061 +- 0.041(stat) +- 0.093(sys) +- 0.042(extrap) per event. |
