Model Independent Limit of the Z-Decay-Width into Unknown Particles
Using the LEP lineshape data combined by the LEP electroweak working group and the left-right asymmetry measured at SLD an almost model independent limit on the decay width of the Z into unpredicted modes is derived. Assuming only that the $\rm{Z} \rightarrow \ee$ and $\rm{Z} \rightarrow \mumu$ deca...

| description | Using the LEP lineshape data combined by the LEP electroweak working group and the left-right asymmetry measured at SLD an almost model independent limit on the decay width of the Z into unpredicted modes is derived. Assuming only that the $\rm{Z} \rightarrow \ee$ and $\rm{Z} \rightarrow \mumu$ decays can be selected cleanly a limit of $\Gnew < 6.3 \MeV$ at 95\% confidence level is derived. |
