Measurement of the branching ratiosb →e ν X, μ ν X, τ ν X andν X
The inclusive semileptonic branching ratios b→eνX,μ νX,τ νX andνX have been measured at LEP with the L3 detector. The analysis is based on 2-jet hadronic Z decays obtained in the data collected between 1991 and 1...

Measurement of cross sections and leptonic forward-backward asymmetries at theZ pole and determination of electroweak parameters
We report on the measurement of the leptonic and hadronic cross sections and leptonic forward-backward asymmetries at theZ peak with the L3 detector at LEP. The total luminosity of 40.8 pb−1 collected in the year...

Search for non-minimal Higgs bosons inZ 0 decays
We report on a search for the neutral and charged Higgs bosons predicted by models of spontaneous symmetry breaking with more than one Higgs doublet field. No signals are observed. We set model-independent lim...

Studies of hadronic event structure and comparisons with QCD models at theZ 0 resonance
The structure of hadronic events fromZ 0 decay is studied by measuring event shape variables, factorial moments, and the energy flow distribution. The distributions, after correction for detector effects and init...

Measurement of electroweak parameters from hadronic and leptonic decays of theZ 0
We have studied the reactionse + e −→hadrons,e + e −, μ+ μ− and τ+ τ−, in the energy range 88.2 \( \leqq \sqrt s \leqq 94.2\) ...
