W pair production cross-section and W branching fractions in e(+)e(-) interactions at 183 GeV

Abstract:

The cross-section for the process e+e-→W+W- has been measured with the data sample collected by DELPHI at an average centre-of-mass energy of 182.65 GeV and corresponding to an integrated luminosity of 53 pb-1. Based on the 770 events selected as WW candidates, the cross-section for the doubly resonant process δ(e+e-→W+W-) = 15.86 ± 0.69 (stat) ± 0.26 (syst)pb has been measured and found to be in good agreement with the Standard Model expectation. The branching fractions of the W decay were a...
