Study of the structure of hadronic events and determination of $\alpha_{s}$ at $\sqrt{s}$ = 130 GeV and 136 GeV / L3 Collaboration
We present a study of the structure of hadronic events recorded by the L3 detector at center-of-mass energies of 130 and 136 GeV. The data sample corresponds to an integrated luminosity of 5 pb-1 collected during the high energy run of 1995. [...]

Study of hadronic events and measurements of $\alpha_{s}$ between 30 and 91 GeV / L3 Collaboration
We have studied the structure of hadronic events with a hard, %radiated isolated photon in the final state ($\mathrm{e^{+}e^{-}} \rightarrow$ Z $\rightarrow$ hadrons $+$ $\gamma$) in the 3.6 million hadronic data collected with the L3 detector at centre-of-mass energies around 91 GeV. The centre-of-mass energy of the hadronic system is in the range 30 GeV to 86 GeV [...]

Search for excited leptons in $e^{+} e^{-}$ annihilation at $\sqrt {s}$ = 130 - 140 GeV / L3 Collaboration
We report on a search for the excited leptons e^*,mu^*,tau^* and nu^* in e+e- collisions at sqrt{s} = 130 - 140 GeV using the L3 detector at LEP. No evidence has been found for their existence. [...]

Production of e, $\mu$ and $\tau$ Pairs in Untagged Two-Photon Collisions at LEP / L3 Collaboration
The two-photon collision reaction e+e- --> e+e-l+l- has been studied at root(s) ~ 91 GeV using the L3 detector at LEP for l = e, muon , tau. We have analysed untagged configurations where the two photons are quasi-real. [...]

QCD Studies and Determination of $\alpha_s$ in $e^+ e^-$ collisions at $\sqrt{s}$ = 161 GeV and 172 GeV / L3 Collaboration
We present a study of the structure of hadronic events recorded by the L3 detector at LEP at the center of mass energies of 161 and 172 GeV. The data sample corresponds to an integrated luminosity of 21.25 pb-1 collected during the high energy runs of 1996. [...]

Measurement of hadron and lepton-pair production at 130 GeV $<$ $\sqrt{s}$ $<$ 140 GeV at LEP / L3 Collaboration
We report on the first measurements of e+e- annihilations into hadrons and lepton pairs at center-of-mass energies between 130 GeV and 140 GeV. In a total luminosity of 5 pb-1 collected with the L3 detector at LEP we select 1577 hadronic and 401 lepton-pair events. [...]

Study of the hadronic photon structure function $F^\gamma_2$ at LEP / L3 Collaboration
The hadronic photon structure function $F^\gamma_2$ is studied in the reaction $\mathrm{e^+e^-} \rightarrow \mathrm{e^+e^-hadrons}$ at LEP with the L3 detector. The data, collected from 1991 to 1995 at a centre-of-mass energy $\sqrt{s} \simeq 91 \GeV$, correspond to an integrated luminosity of 140~pb$^{-1}$. [...]
