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. [...]

Measurement of $\eta '(958)$ formation in two-photon collisions at LEP1 / L3 Collaboration
The formation of the eta' in the reaction ee->ee eta'->ee pi pi gamma has been measured by the L3 detector at a centre-of-mass energy of 91 GeV. The radiative width of the eta' has been found to be 4.17 +/- 0.10(stat.) +/- 0.27(sys.) keV . [...]

The Q$^2$ evolution of the Hadronic Photon Structure Function $F^\gamma_2$ at LEP / L3 Collaboration
New measurements at a centre-of-mass energy of 183 GeV of the hadronic photon structure function F2(x) in the Q2 interval, 9 GeV2 < Q2 < 30 GeV2, are presented. The data, collected in 1997, with the L3 detector, correspond to an integrated luminosity of 51.9 pb-1. [...]

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$^{-1}$. [...]

Determination of the number of light neutrino species from single photon production at LEP / L3 Collaboration
A determination of the number of light neutrino families performed by measuring the cross section of single photon production in \ee\ collision near the \Zo\ resonance is reported. From an integrated luminosity of $100~\mathrm{pb^{-1}}$, collected during the years 1991--94, we have observed 2091 single photon candidates with an energy above 1~\GeV\ in the polar angular region $45^\circ < \theta_\gamma < 135^\circ$ [...]

Measurement of the cross-section for the process $\gamma^* \gamma^* \to$ hadrons at LEP / L3 Collaboration
Measurements of the two-photon interaction e+e- --> e+e- hadrons at sqrt(s) = 91 GeV and sqrt(s) = 183 GeV are presented. The double-tag events, collected with the L3 detector, correspond to integrated luminosities of 140 pb-1 at 91 GeV and 52 pb-1 at 183 GeV. [...]

$\chi_{c2}$ formation in two-photon collisions at LEP ; rev. version / L3 Collaboration
Two-photon formation of the charmonium resonance $\chi_{{\rm c}2}$ has been studied with the L3 detector at LEP. The $\chi_{{\rm c}2}$ is identified through its decay $\chi_{{\rm c}2} \rightarrow \gamma {\rm J}$, with a subsequent decay ${\rm J} \rightarrow {\mathrm{e^+ e^-}}$ or ${\rm J} \rightarrow {\mathrm{\mu^+ \mu^-}}$.

Measurement of Branching Fractions of $\tau$ Hadronic Decays / L3 Collaboration
Using data collected with the L3 detector at LEP at the Z peak, the branching fractions of the $\tau$ lepton into the hadronic final states, $h^- n\pi^0 \nu(n=0,1,2, >= 3)$ and $h^-h^+h^- n\pi^0 \nu$ where $h^\pm$ denotes a charged hadron, are measured to be .....
