Measurement of Mass and Width of the W Boson at LEP / L3 Collaboration
We report on measurements of the mass and total decay width of the W boson with the L3 detector at LEP. W-pair events produced in e+e- interactions between 161 GeV and 183 GeV centre-of-mass energy are selected in a data sample corresponding to a total luminosity of 76.7 pb-1. [...]

Measurement of the W-Pair Production Cross Section and W-Decay Branching Fractions in $e^{+}e^{-}$ Interactions at $\sqrt{s}$= 189 GeV / L3 Collaboration
The data collected by the L3 experiment at LEP at a centre-of-mass energy of $188.6~\rm{Ge\kern -0.1em V}$ are used to measure the W-pair production cross section and the W-boson decay branching fractions. These data correspond to an integrated luminosity of 176.8~pb$^{-1}$. [...]

Measurement of Triple-Gauge-Boson Couplings of the W Boson at LEP / L3 Collaboration
We report on measurements of the triple-gauge-boson couplings of the W boson in $\mathrm{e^+e^-}$ collisions with the L3 detector at LEP. W-pair, single-W and single-photon events are analysed in a data sample corresponding to a total luminosity of 76.7~pb$^{-1}$ collected at centre-of-mass energies between 161~GeV and 183~GeV. [...]

Measurement of Bose-Einstein Correlations in $e^{+}e^{-}\to W^{+}W^{-}$ Events at LEP / L3 Collaboration
Bose-Einstein correlations in W-pair production at LEP are investigated in a data sample of 629 pb$^{-1}$ collected by the L3 detector at $\sqrt{s}=$ 189--209\,GeV. Bose-Einstein correlations between pions within a W decay are observed and found to be in good agreement with those in light-quark Z decay. [...]

Measurement of the W-pair Production Cross-section and W Branching Ratios in $e^+ e^-$ Collisions at $\sqrt{s}$ = 161-209 GeV / DELPHI Collaboration
These final results on e+e- -> W+W- production cross-section measurements at LEP2 use data collected by the DELPHI detector at centre-of-mass energies up to 209 GeV. Measurements of total cross-sections, W angular differential distributions and decay branching fractions, and the value of the CKM element |V_{cs}| are compared to the expectations of the Standard Model.

Measurement of Bose-Einstein Correlations in $e^{+}e^{-} \to W^{+}W^{-}$ at $\sqrt{s}\simeq$ 189 GeV / L3 Collaboration
We investigate \BE\ correlations (BEC) in W-pair production at $\sqrt{s}\simeq189 \GeV$ using the L3 detector at LEP. We observe BEC between particles from a single W~decay in good agreement with those from a light-quark Z~decay sample. [...]

Measurement of the mass and the width of the W boson at LEP / L3 Collaboration
The mass and the total decay width of the W boson are measured with the L3 detector at the LEP e+e- collider using W-boson pairs produced in 0.7/fb of data collected at centre-of-mass energies between 161 and 209GeV. Combining semi-leptonic and fully-hadronic final states, the mass and the width of the W boson are determined to be mW = 80.270 +/- 0.046 +/- 0.031 GeV and GW = 2.18 +/- 0.11 +/- 0.09 GeV, where the first uncertainty is statistical and the second systematic..

$W^{+}W^{-}$ Production Cross Section and W Branching Fractions in $e^{+}e^{-}$ Collisions at 189 GeV / OPAL Collaboration
From a data sample of 183 pb^-1 recorded at a center-of-mass energy of roots = 189 GeV with the OPAL detector at LEP, 3068 W-pair candidate events are selected. Assuming Standard Model W boson decay branching fractions, the W-pair production cross section is measured to be sigmaWW = 16.30 +- 0.34(stat.) +- 0.18(syst.) pb. [...]

Search for Charged Higgs Bosons at LEP in General Two Higgs Doublet Models / DELPHI Collaboration
A search for pair-produced charged Higgs bosons was performed in the data collected by the DELPHI detector at LEP II at centre-of-mass energies from 189 GeV to 209 GeV. Five different final states, tau+ nu_tau tau- anti-nu_tau, c sbar cbar s, c sbar tau- anti-nu_tau, W* A W* A and W* A tau- anti-nu_tau were considered, accounting for the major expected decays in type I and type II Two Higgs Doublet Models.

Search for resonant $\widetilde\nu$ production at $\sqrt{s}$ = 183 to 208 GeV / DELPHI Collaboration
Searches for resonant sneutrino production in e+e- collisions under the assumption that R-parity is not conserved and that the dominant R-parity violating coupling is lambda_{121} or lambda_{131} used data recorded by DELPHI in 1997 to 2000 at centre-of-mass energies of 183 to 208 GeV. No deviation from the Standard Model was observed. [...]
