Study of the Solar Anisotropy for Cosmic Ray Primaries of about 200 GeV Energy with the L3+C Muon Detector / L3 Collaboration
Primary cosmic rays experience multiple deflections in the nonuniform galactic and heliospheric magnetic fields which may generate anisotropies. A study of anisotropies in the energy range between 100 and 500 GeV is performed. [...]

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 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 .....

The Solar Flare of the 14th of July 2000 (L3+C detector results) / L3 Collaboration
Several experiments have reported observations on possible correlations between the flux of high energy muons and intense solar flares. If confirmed, these observations would have significant implications for acceleration processes in the heliosphere able to accelerate protons and other ions to energies of at least tens of GeV. [...]

Inclusive $D^{*\pm}$ production in two-photon collisions at LEP / L3 Collaboration
Inclusive D*/sup +or-/ production in two-photon collisions is studied with the L3 detector at LEP, using 683 pb/sup -1/ of data collected at centre-of-mass energies from 183 to 209 GeV. Differential cross sections are determined as functions of the transverse momentum and pseudorapidity of the D*/sup +or-/ mesons in the kinematic region 1 GeV<P/sub T/<12 GeV and $\beta$ <1.4. [...]

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..

A search for flaring Very-High-Energy cosmic-ray sources with the L3+C muon spectrometer / L3 Collaboration
The L3+C muon detector at the Cern electron-position collider, LEP, is used for the detection of very-high-energy cosmic \gamma-ray sources through the observation of muons of energies above 20, 30, 50 and 100 GeV. Daily or monthly excesses in the rate of single-muon events pointing to some particular direction in the sky are searched for. [...]
