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...

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...

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...
