Electroweak Measurements in Electron-Positron Collisions at W-Boson-Pair Energies at LEP / ALEPH Collaboration
Electroweak measurements performed with data taken at the electron-positron collider LEP at CERN from 1995 to 2000 are reported. The combined data set considered in this report corresponds to a total luminosity of about 3~fb$^{-1}$ collected by the four LEP experiments ALEPH, DELPHI, L3 and OPAL, at centre-of-mass energies ranging from $130~GeV$ to $209~GeV$ [...]

Precision electroweak measurements on the $Z$ resonance / ALEPH Collaboration
We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLD experiment using a polarised beam at SLC. [...]

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 [...]

Search for the Standard Model Higgs Boson at LEP / ALEPH Collaboration
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have collected a total of 2461 pb-1 of e+e- collision data at centre-of-mass energies between 189 and 209 GeV. The data are used to search for the Standard Model Higgs boson. [...]

Bose-Einstein Correlations of $\pi^{0}$ Pairs from Hadronic $Z^{0}$ Decays / OPAL Collaboration
We observed Bose-Einstein correlation in pi0 pairs produced in Z0 decays using the data sample collected by the OPAL detector at LEP 1 from 1991 to 1995. Using a static Gaussian picture for the pion emitter source, we obtain the chaoticity parameter lambda = 0.55 +- 0.10 +- 0.10 and the source radius R = (0.59 +- 0.08 +- 0.05) fm. [...]

A Measurement of Semileptonic B Decays to Narrow Orbitally-Excited Charm Mesons / OPAL Collaboration
The decay chain b -> Bbar -> D^{**0} l nu X, D^{**0} -> D^{*+} pi^-, D^{*+} -> D^0 pi^+, D^0 ->(Kpi or K3pi) is identified in a sample of 3.9 million hadronic Z decays collected with the OPAL detector at LEP. The branching ratio BR (b -> Bbar) x BR (Bbar -> D^0_1 l nu X) x BR (D^0_1 -> D^{*+} pi^-) is measured to be (2.64 +- 0.79 (stat) +- 0.39 (syst)) X 10^-3 for the J^P = 1^+ (D^0_1) state. [...]
