f$_1$(1285) Formation in Two-Photon Collisions at LEP / L3 Collaboration
The $\eta \pi^+ \pi^-$ final state in two-photon collisions is studied with the L3 detector at LEP, at centre-of-mass energies from 183 to 209~GeV with an integrated luminosity of 664.6~pb$^{-1}$. The f$_1$(1285) meson is observed and the $Q^2$ dependence of its production is compared to different form factor models. [...]

Light Resonances in $K^{0}_{S} K^{\pm}\pi^{\mp}$ and $\eta \pi^{+}\pi^{-}$ final states in $\gamma\gamma$ collisions at LEP / L3 Collaboration
The $e^+ e^- \rightarrow e^+ e^- K^{0}_{s} K^{\pm} pi^{\mp}$ and $e^+ e^- \rightarrow e^+ e^- \eta \pi^{+} \pi^{-}$ final states are studied with the L3 detector at LEP using data collected at centre-of-mass energies from 183 GeV up to 202 GeV. The mass spectrum of the $K^{0}_{s} K^{\pm} \pi^{\mp}$ final state shows an enhancement around 1470 MeV, which is identified with the pseudoscalar meson $\eta(1440)$. [...]

The $\eta_c$(2980) formation in two-photon collisions at LEP energies / DELPHI Collaboration
eta_c(2980) production in gamma-gamma interactions has been detected via its decays into K0_s K+/- pi-/+, K+ K- K+ K- and K+ K- pi+ pi- in the data taken with the DELPHI detector at LEP1 and LEP2 energies. The two-photon radiative width averaged over all observed decay channels is \Gamma_{\gamma\gamma} = 13.9 +/- 2.0 (stat.) +/- 1.4 (syst.) +/- 2.7 (BR) keV. [...]

Z-boson production with two unobserved, back-to-back, hard photons at LEP / L3 Collaboration
The double-radiative process e+e- -> Z gamma gamma -> q q~ gamma gamma, where the two hard photons escape detection at low polar angles into opposite directions, is studied in 0.62/fb of data collected with the L3 detector at LEP at centre-of-mass energies between 188.6GeV and 209.2GeV. The cross sections are measured and found to be consistent with the Standard Model expectations..

Inclusive $\Sigma^{+}$ and $\Sigma^{0}$ Production in Hadronic Z Decays / L3 Collaboration
We report on measurements of the inclusive production rate of $\Sigma^+$ and $\Sigma^0$ baryons in hadronic Z decays collected with the L3 detector at LEP. The $\Sigma^+$ baryons are detected through the decay $\Sigma^+ \rightarrow {\rm p} \pi^0$, while the $\Sigma^0$ baryons are detected via the decay mode $\Sigma^0 \rightarrow \Lambda \gamma$. [...]

Measurement of Inclusive $f_1$(1285) and $f_1$(1420) Production in Z Decays with the DELPHI Detector / DELPHI Collaboration
DELPHI results are presented on the inclusive production of two (K Kbar pi)^0 states in the mass region 1.2-1.6 GeV/c^2 in hadronic Z decays at LEP I. The measured masses (widths) are 1274 +/- 6 MeV/c^2 (29 +/- 12 MeV/c^2) and 1426 +/- 6 MeV/c^2 (51 +/- 14 MeV/c^2) respectively. [...]

Analysis of the $\pi^+ \pi^- \pi^+ \pi-$ and $\pi^+ \pi^{0}\pi^- \pi^{0}$ final states in quasi-real two-photon collisions at LEP / L3 Collaboration
The reactions gamma gamma -> pi^+pi^-pi^+pi^- and gamma gamma -> pi^+pi^0pi^-pi^0 are studied with the L3 detector at LEP in a data sample collected at centre-of-mass energies from 161GeV to 209GeV with a total integrated luminosity of 698/pb. A spin-parity-helicity analysis of the rho^0 rho^0 and rho^+ rho^- systems for two-photon centre-of-mass energies between 1GeV and 3GeV shows the dominance of the spin-parity state 2+ with helicity 2.

Higgs Candidates in $e^{+}e^{-}$ Interactions at $\sqrt{s}$ = 206.6 GeV / L3 Collaboration
In a search for the Standard Model Higgs boson, carried out on 212.5 pb-1 of data collected by the L3 detector at the highest LEP centre-of-mass energies, including 116.5 pb-1 above root(s) = 206GeV, an excess of candidates for the process e+e- -> Z* -> HZ is found for Higgs masses near 114.5GeV. We present an analysis of our data and the characteristics of our strongest candidates..

Measurement of the Atmospheric Muon Spectrum from 20 to 3000 GeV / L3 Collaboration
The absolute muon flux between 20 GeV and 300 GeV is measured with the L3 magnetic muon spectrometer for zenith angles ranging from 0 degree to 58 degrees. Due to the large exposure of about 150 m2 sr d, and the excellent momentum resolution of the L3 muon chambers, a precision of 2.3% at 150 GeV in the vertical direction is achieved. [...]

$\Lambda$ and $\Sigma^{0}$ Pair Production in Two-Photon Collisions at LEP / L3 Collaboration
Strange baryon pair production in two-photon collisions is studied with the L3 detector at LEP. The analysis is based on data collected at e+e- centre-of-mass energies from 91 GeV to 208 GeV, corresponding to an integrated luminosity of 844 pb-1. [...]
