The absolute muon flux between 20 and 3000 GeV is measured with the L3 magnetic muon spectrometer for zenith angles ranging from 0 • to 58 •. Due to the large exposure of about 150 m 2 sr d, and the excellent momentum resolution of the L3 muon chambers, a precision of 2.3% at 150 GeV in the vertical direction is achieved. The ratio of positive to negative(More)
This note presents a combination of published and preliminary electroweak results from the four LEP collaborations and the SLD collaboration which were prepared for the 1996 summer conferences. Averages of the results concerning electroweak physics are presented. They are derived from the measurements of hadronic and leptonic cross sections, the leptonic(More)
Using data collected with the L3 detector at LEP from 1992 to 1995 on the Z peak, we determine the branching fractions of the τ lepton into one, three and five charged particles to be: The first uncertainties are statistical and the second systematic. The accuracy of these measurements alone is similar to that of the current world average.
The QED processes e+e− → e+e−μ+μ− and e+e− → e+e−τ+τ− are studied with the L3 detector at LEP using an untagged data sample collected at centre-of-mass energies 161 GeV √s 209 GeV. The τ -pairs are observed through the associated decay of one τ into eνν and the other into ππν. The cross sections are measured as a function of √ s. For muon pairs, the cross(More)

Precision measurements at the Z-boson resonance using electron{positron colliding beams began in 1989 at the SLC and at LEP. During 1989{95, the four CERN experiments have made high-statistics studies of the Z. The availability of longitudinally polarized electron beams at the SLC since 1993 has enabled a precision determination of the eeective electroweak(More)
