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 189 GeV and corresponding to an integrated luminosity of 155 pb-1. Based on the 2392 events selected as WW candidates, the cross-section for the doubly resonant process e+ e- → W+ W- has been measured to be 15.83 ± 0.38 (stat) ± 0.20 (syst)pb. The branching fractions of the W decay were also measured and found to be in good agreement with the Standard Model expectation. From these a value of the CKM mixing matrix element |V(cs)| = 1.001 ± 0.040 (stat) ± 0.020 (syst) was derived. (C) 2000 Elsevier Science B.V.
