Measurement of the W-pair production cross section and W-decay branching fractions in e+e− interactions at s=189 GeV
Abstract
The data collected by the L3 experiment at LEP at a centre-of-mass energy of 188.6 GeV are used to measure the W-pair production cross section and the W-boson decay branching fractions. These data correspond to an integrated luminosity of 176.8 pb−1. The total cross section for W-pair production, combining all final states, is measured to be σWW=16.24±0.37 (stat.)±0.22 (syst.) pb. Including our data collected at lower centre-of-mass energies, …
