    AbstractThe cross section of W-boson pair-production is measured with the L3 detector at LEP. In a data sample corresponding to a total luminosity of 629.4  pb − 1 , collected at centre-of-mass energies ranging from 189 to 209 GeV, 9834 four-fermion events with W bosons decaying into hadrons or leptons are selected. The total cross section is measured with a precision of 1.4% and agrees with the Standard Model expectation. Assuming charged-lepton universality, the branching fraction for hadronic W-boson decays is measured to be: Br ( W → hadrons ) = 67.50 ± 0.42 ( stat. ) ± 0.30 ( syst. ) % , in agreement with the Standard Model. Differential cross sections as a function of the W − production angle are also measured for the semi-leptonic channels qqeν and qq μ ν .
