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. [...]

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. [...]

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 .....

Aging tests of full-scale CMS muon cathode strip chambers / Acosta, D (U. Florida, Gainesville (main)) ; Apollinari, G (Fermilab) ; Arisaka, K ; Bondar, N ; Breedon, R ; Bujak, A ; Bylsma, B ; Chester, N (Fermilab) ; Clare, R ; Cline, D et al.
Two CMS production Cathode Strip Chambers were tested for aging effects in a high-radiation environment at the Gamma Irradiation Facility at CERN. The chambers were irradiated over a large area: in total, about 2.1m**2 or 700m of wire in each chamber. [...]

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. [...]

Helium in near Earth orbit / AMS Collaboration
The helium spectrum from 0.1 to 100 GeV/nucleon was measured by the Alpha Magnetic Spectrometer (AMS) during space shuttle flight STS-91 at altitudes near 380 km. Above the geomagnetic cutoff the spectrum is parameterized by a power law. [...]

Measurements of the $b\overline{b}$ production cross section and forward-backward asymmetry at centre-of-mass energies above the Z pole at LEP / L3 Collaboration
The measurements of R/sub b/= sigma (e/sup +/e/sup -/ to bb)/ sigma (e/sup +/e/sup -/ to qq) and of the b quark forward-backward charge asymmetry, A/sub fb//sup b/, at centre-of-mass energies above the Z pole are described. The measurement of R/sub b/ is performed at square root (s) between 130 and 189 GeV using a b-tagging method that exploits the relatively large decay length of b-hadrons. [...]

Photon structure functions and azimuthal correlations of lepton pairs in tagged $\gamma\gamma$ collisions / L3 Collaboration
Measurements of the QED structure of the photon based on the reaction ee to ee gamma /sup (*)/(P/sup 2/) gamma *(Q/sup 2/) to ee mu mu are discussed. This review is an update of the discussion of the results on the QED structure of the photon and covers the published measurements of the photon structure functions F/sub 2//sup gamma /, F/sub A//sup gamma / and F/sub B//sup gamma / and of the differential cross-section d sigma /dx for the exchange of two virtual photons.
