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. [...]

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. [...]

Inclusive $D^{*\pm}$ production in two-photon collisions at LEP / L3 Collaboration
Inclusive D*/sup +or-/ production in two-photon collisions is studied with the L3 detector at LEP, using 683 pb/sup -1/ of data collected at centre-of-mass energies from 183 to 209 GeV. Differential cross sections are determined as functions of the transverse momentum and pseudorapidity of the D*/sup +or-/ mesons in the kinematic region 1 GeV<P/sub T/<12 GeV and $\beta$ <1.4. [...]

Search for Single Top Production at LEP / L3 Collaboration
Single top production in e^+e^- annihilations is searched for in data collected by the L3 detector at centre-of-mass energies from 189 to 209 GeV, corresponding to a total integrated luminosity of 634 pb-1. Investigating hadronic and semileptonic top decays, no evidence of single top production at LEP is obtained and upper limits on the single top cross section as a function of the centre-of-mass energy are derived.

Search for Neutral Higgs Bosons of the Minimal Supersymmetric Standard Model in $e^{+}e^{-}$ Interactions at $\sqrt{s}$ up to 209 GeV / L3 Collaboration
A search for the lightest neutral CP-even and neutral CP-odd Higgs bosons of the Minimal Supersymmetric Standard Model is performed using 216.6 pb-1 of data collected with the L3 detector at LEP at centre-of-mass energies between 203 and 209 GeV. No indication of a signal is found. [...]

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. [...]
