New constraints on the $\tau$ neutrino mass and fourth generation mixing
We present new constraints on the mass $m_{\nu_\tau}$ of the tau neutrino and its mixing with a fourth generation neutrino. From an analysis of the partial widths of tau lepton decays we obtain the following bounds at the 90% confidence level: $m_{\nu_\tau} < 32$ MeV and $\sin^2\theta < 0.007$...
