K0s K0s Final State in Two-Photon Collisions and Implications for Glueballs
L3 Collaboration
The K0s K0s 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 helic…
Light resonances in Ks K pi and eta pi pi final states in gamma gamma collisions at LEP
L3 Collaboration
The e+e- -> e+e- Ks K+- pi-+ e+e- -> e+e- eta pi+ pi- and final states are studied with the L3 detector at LEP using data collected at centre-of-mass energies from 183 GeV up to 20…
Measurement of the W-Pair Production Cross Section and W-Decay Branching Fractions in e+e- Interactions at sqrt{s}=189GeV
L3 Collaboration
The data collected by the L3 experiment at LEP at a centre-of-mass energy of 188.6 GeV are used to measure the W-pair production cross section and the W-boson decay branching fract…
Search for anomalous couplings in the Higgs sector at LEP
L3 Collaboration
We search for a Higgs particle with anomalous couplings in the e+e- -> H gamma, e+e- -> HZ and e+e- -> He+e- processes with the L3 detector at LEP. We explore the mass range 70GeV…
Measurement of the W+W-gamma Cross Section and Direct Limits on Anomalous Quartic Gauge Boson Couplings at LEP
L3 Collaboration
The process e+e- -> W+W-gamma is analysed using the data collected with the L3 detector at LEP at a centre-of-mass energy of 188.6GeV, corresponding to an integrated luminosity of…
Determination of gamma/Z interference in e+e- annihilation at LEP
L3 Collaboration
An S-Matrix ansatz is used to determine the mass and width of the Z boson, as well as the contributions of gamma/Z interference and Z boson exchange to fermion-pair production. For…
QCD studies in e+e- annihilation from 30GeV to 189GeV
L3 Collaboration
We present results obtained from a study of the structure of hadronic events recorded by the L3 detector at various centre-of-mass energies. The distributions of event shape variab…

L3 Collaboration
We search for anomalous trilinear gauge couplings in the ZZgamma and Zgammagamma vertices using data collected with the L3 detector at LEP at a centre-of-mass energy \sqrt{s}=189 G…
Measurement of the Lifetime of the Tau Lepton
L3 Collaboration
The tau lepton lifetime is measured with the L3 detector at LEP using the complete data taken at centre-of-mass energies around the Z pole resulting in tau_tau = 293.2 +/- 2.0 (sta…
Inclusive Sigma+ and Sigma0 Production in Hadronic Z Decays
L3 Collaboration
We report on measurements of the inclusive production rate of Sigma+ and Sigma0 baryons in hadronic Z decays collected with the L3 detector at LEP. The Sigma+ baryons are detected…
