A full-acceptance detector at the LHC (FELIX) / FELIX Collaboration
The FELIX collaboration had proposed the construction of a full- acceptance detector for the LHC. The primary mission of FELIX was the study of QCD: to provide comprehensive and definitive observations of a very broad range of strong-interaction processes. [...]

Photon structure functions and azimuthal correlations of lepton pairs in tagged $\gamma\gamma$ collisions / L3 Collaboration
Measurements of the QED structure of the photon based on the reaction ee to ee gamma /sup (*)/(P/sup 2/) gamma *(Q/sup 2/) to ee mu mu are discussed. This review is an update of the discussion of the results on the QED structure of the photon and covers the published measurements of the photon structure functions F/sub 2//sup gamma /, F/sub A//sup gamma / and F/sub B//sup gamma / and of the differential cross-section d sigma /dx for the exchange of two virtual photons. [...]

Search for extra dimensions in boson and fermion pair production in $e^{+}e^{-}$ interactions at LEP / L3 Collaboration
Extra spatial dimensions are proposed by recent theories that postulate the scale of gravity to be of the same order as the electroweak scale. A sizeable interaction between gravitons and Standard Model particles is then predicted. [...]

Search for neutral higgs bosons of the minimal supersymmetric standard model in $e^{+}e^{-}$ Interactions at $\sqrt{s}= 189$ GeV / L3 Collaboration
A search for the lightest neutral scalar and neutral pseudoscalar Higgs bosons in the Minimal Supersymmetric Standard Model is performed using 176.4 pb$^{-1}$ of integrated luminosity collected by L3 at a center-of-mass energy of 189 GeV. No signal is observed, and the data are consistent with the expected Standard Model background. [...]

Search for Excited Leptons at $\sqrt{s}$= 189 GeV / L3 Collaboration
A search for excited leptons, $\rm e^*,~\mu^*, ~\tau^*, ~\nu_e^*, ~\nu_{\mu}^*$ and $\nu_{\tau}^*$, was performed with the L3 detector at LEP using data collected at a centre--of--mass energy of 189 GeV, corresponding to an integrated luminosity of $\rm 176~pb^{-1}$. No evidence of their production is observed. [...]

Searches for scalar quarks in $e^{+}e^{-}$ interactions at $\sqrt{s}$= 189 GeV / L3 Collaboration
Searches for scalar top and scalar bottom quarks, as well as for mass-degenerate scalar quarks of the first two families are performed at 189 GeV centre-of-mass energy with the L3 detector at LEP. No signals are observed. [...]

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. [...]

Single and Multi-Photon Events with Missing Energy in $e^{+}e^{-}$ Collisions at $\sqrt{s}$ = 189 GeV / L3 Collaboration
Single and multi-photon events with missing energy are analysed using data collected with the L3 detector at LEP at a centre-of-mass energy of 189 GeV, for a total of 176 pb$^{-1}$ of integrated luminosity. The cross section of the process $\rm e^+e^-\rightarrow\nu\bar{\nu}\gamma(\gamma)$ is measured and the number of light neutrino flavours is determined to be \( N_\nu = 3.011 \pm 0.077 \) including lower energy data.
