Search for neutral Higgs bosons of the minimal supersymmetric standard model in $e^{+} e^{-}$ interactions at $\sqrt{s}$ = 192-GeV - 202-GeV
[CERN-EP-2000-145; hep-ex/0012017] ddc:530
A search for the lightest neutral CP-even and the neutral CP-odd Higgs bosons of the Minimal Supersymmetric Standard Model is performed using 233.2 pb-1 of integrated luminosity collected with the L3 detector at LEP at centre-of-mass energies 192-202 GeV. No signal is observed and lower mass limits are given as a function of tan(beta) for two scalar top mixing hypotheses. [...]

Higgs candidates in $e^{+} e^{-}$ interactions at $\sqrt{s}$ = 206.6-GeV
[CERN-EP-2000-140; hep-ex/0011043] ddc:530
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 s =206  GeV, an excess of candidates for the process e + e − → Z ∗ → HZ is found for Higgs masses near 114.5 GeV. We present an analysis of our data and the characteristics of our strongest candidates..

Measurements of the cross-sections for open charm and beauty production in $\gamma \gamma$ collisions at $\sqrt{s}$ = 189-GeV to 202-GeV
[CERN-EP-2000-144; hep-ex/0011070] ddc:530
The production of c and b quarks γγ collisions is studied with the L3 detector at LEP with 410 pb −1 of data, collected at centre-of-mass energies from 189 GeV to 202 GeV. Hadronic final states containing c and b quarks are identified by detecting electrons or muons from their semileptonic decays. [...]

$K^0_{S} K^0_{S}$ final state in two photon collisions and implications for glueballs
[CERN-EP-2000-135; hep-ex/0011037] ddc:530
The K 0 S K 0 S final state in two-photon collisions is studied with the L3 detector at LEP. The mass spectrum is dominated by the formation of the f ′ 2 (1525) tensor meson in the helicity-two state with a two-photon width times the branching ratio into K K ̄ of 76±6±11 eV. [...]

[CERN-EP-2000-120; hep-ex/0010004] ddc:530
The cross section for the production of Z boson pairs is measured using the data collected by the L3 detector at LEP in 1999 in e + e − collisions at centre-of-mass energies ranging from 192 GeV up to 202 GeV. Events in all the visible final states are selected, measuring the cross section of this process. [...]
