Measurement of the mass of the W boson in $e^{+}e^{-}$ collisions using the fully leptonic channel / OPAL Collaboration
A novel method of determining the mass of the W boson in the W/sup + /W/sup -/ to l nu l' nu ' channel is presented and applied to 667 pb /sup -1/ of data recorded at center-of-mass energies in the range 183-207 GeV with the OPAL detector at LEP. The measured energies of charged leptons and the results of a new procedure based on an approximate kinematic reconstruction of the events are combined to give: M/sub W/=80.41+or-0.41+or-0.13 geV, where the first error is statistical and the second is systematic.

A measurement of the $\tau^{-} \to \mu^{-} \nu_{\mu} \nu_{\tau}$ branching ratio / OPAL Collaboration
The tau /sup -/ to mu /sup -/ nu /sub mu / nu /sub tau / branching ratio has been measured using data collected from 1990 to 1995 by the OPAL detector at the LEP collider. The resulting value of B( tau /sup -/ to mu /sup -/ nu /sub mu / nu /sub tau /) = 0.1734 +or- 0.0009 (stat) +or- 0.0006(syst) has been used in conjunction with other OPAL measurements to test lepton universality, yielding the coupling constant ratios g/sub mu //g/sub e/ = 1.0005 +or- 0.0044 and g/sub tau //g/sub e/ = 1.0031 +or- 0.0048, in good agreement with the Standard Model prediction of unity [...]
