Search for Scalar Leptons in $e^+ e^-$ collisions at $\sqrt{s}$= 183 GeV / L3 Collaboration
We report the result of a search for scalar leptons in $\mathrm{ e^+ e^-}$ collisions at 183 GeV centre-of-mass energy at LEP. No evidence for such particles is found in a data sample of 55.2 pb$^{-1}$. [...]

Study of resonance formation in the mass region 1400 - 1500 MeV through the reaction $\gamma\gamma \to K^{0}_{S} K^{\pm} \pi^{\mp}$ / L3 Collaboration
The K^0_SK^+-\pi-+ final state in two-photon collisions is studied with the L3 detector at LEP at e+e- centre-of-mass energies from 183 to 209 GeV with an integrated luminosity of 664.6 pb-1. The \eta(1475) and f1(1420) mesons are observed and their contribution is separated by measuring the formation rates as a function of the photon virtuality Q2. [...]

Search for neutral Higgs bosons of the Minimal Supersymmetric Standard Model in $e^+ e^-$ interactions at $\sqrt{s}$ = 130-183 GeV / L3 Collaboration
A search for the lightest neutral scalar and neutral pseudoscalar Higgs bosons in the Minimal Supersymmetric Standard Model is performed on data collected at LEP by the L3 detector at center-of-mass energies 130 GeV <= Sqrt(s) <= 183 GeV. No significant excess of events is observed. [...]

Study of Neutral-Current Four-Fermion and ZZ Production in $e^+ e^-$ Collisions at $\sqrt{s}$= 183 GeV / L3 Collaboration
Study of Neutral--Current Four--Fermion and ZZ \\ Production in $\rm e^+ e^-$ Collisions at $\rm \sqrt{s}=$ 183 GeV A study of neutral--current four--fermion processes is performed using a data sample corresponding to 55.3~pb$^{-1}$ of integrated luminosity collected by the L3 detector at LEP at an average centre--of--mass energy of $183~\GeV$. The neutral--current four--fermion cross sections for final states with a pair of charged leptons plus jets and with four charged leptons are measured to be consistent with the Standard Model predictions.

Search for charged Higgs bosons in $e^+ e^-$ collisions at centre-of-mass energies between 130 and 183 GeV / L3 Collaboration
A search for pair-produced charged Higgs bosons is performed with the L3 detector at LEP using data collected at centre-of-mass energies from \mbox{130 to 183 \GeV{}}, corresponding to an integrated luminosity of 88.3 \pb. The Higgs decays into a charm and a strange quark or into a tau lepton and its associated neutrino are considered. [...]

Search for scalar leptons, charginos and neutralinos in $e^{+} e^{-}$ collisions at $\sqrt{s}$ = 161-172 GeV / L3 Collaboration
Scalar leptons, charginos and neutralinos, predicted by supersymmetric theories, have been searched for in data samples collected with the L3 detector at centre-of-mass energies of 161 GeV and 172 GeV with integrated luminosities of 10.7 pb$^{-1}$ and 10.0 pb$^{-1}$ respectively. No evidence for such particles is found. [...]

Production of single W bosons in $e^+ e^-$ interactions at $130 \leq \sqrt{s} \leq 183 GeV$ and limits on anomalous $WW\gamma$ couplings / L3 Collaboration
We report on a study of single W boson production in a data sample collected by the L3 detector at centre-of-mass energies from 130 to 183 GeV. The signal consists of large missing energy final states with a single energetic lepton or two hadronic jets. [...]

Search for R-parity Violating Chargino and Neutralino Decays in $e^+ e^-$ Collisions up to $\sqrt{s}$= 183 GeV / L3 Collaboration
A search for chargino and neutralino pair production in $\mathrm{ e^+e^-}$ collisions at center-of-mass energies between 161~\textrm{Ge\kern -0.1em V} and 183~\textrm{Ge\kern -0.1em V} is performed under the assumptions that R-parity is not conserved and that only purely leptonic or hadronic R-parity violating decays are allowed. No signal is found in the data. [...]
