A measurement of the V-A x V-A structure of the weak charged current in semileptonic b decays and missing energy measurements / Behner, Frank (Zurich, ETH)
The polarization of the W-propagator in semileptonic b decays is measured with the 13 experiment at LEP via simultaneous observation of the charged lepton and the neutrino spectrum. The polarization is seen with more than 3 standard deviations and found to be in agreement with the V-AxV-A structure. [...]

Measurement of the mass of the W boson at LEP and determination of electroweak parameters / Straessner, A (Aachen, Tech. Hochsch.)
Precise measurements of the W mass and width performed at LEP are presented, which yield $M_W$ = 80.427 ± 0.046 GeV and $Γ_W$ = 2.12 ± 0.11 GeV. A comparison is made between this direct determination and the W mass value obtained indirectly in an analysis of other electroweak measurements. [...]
