Pair-production of W bosons in e+e- interactions at √s = 161 GeV

We report on the measurement of W-boson pair-production with the L3 detector at LEP at a centre-of-mass energy of 161.34 GeV. In a data sample corresponding to a total luminosity of 11 pb<sup>−1</sup>, we select four-fermion events with high invariant masses of pairs of hadronic jets or...

description We report on the measurement of W-boson pair-production with the L3 detector at LEP at a centre-of-mass energy of 161.34 GeV. In a data sample corresponding to a total luminosity of 11 pb<sup>−1</sup>, we select four-fermion events with high invariant masses of pairs of hadronic jets or leptons. Combining all final states, the measured total cross section for W-pair production is: sigma<sub>WW</sub> = 2.89<sup>+0.81</sup><sub>-0.42</sub>(stat.) ± 0.14 (syst.) pb. Within the Standard Model, this corresponds to a mass of the W boson of: M<sub>W</sub> = 80.80<sup>+0.48</sup><sub>-0.42</sub> (exp.) ± 0.03 (LEP) GeV. Limits on anomalous triple-vector-boson couplings are derived.
