Abstract

In 1996 LEP ran at a centre-of-mass energy of 161 GeV, just above the threshold of W-pair production. DELPHI accumulated data corresponding to an integrated luminosity of 9.93 pb-1, and observed 29 events that are considered as candidates for W-pair production. From these, a cross-section for the doubly resonant e+e- -> WW process of 3.67+0.97-0.85± 0.19 pb has been measured. Within the Standard Model, this cross-section corresponds to a mass of the W-boson of 80.40 ± 0.44(stat.) ±0.09(syst.) ±0.03(LEP) GeV/c2. Alternatively, if mwis held fixed at its current value determined by other experiments, the observed cross-section is used to obtain limits on trilinear WWV(V ≡, Z) couplings. © 1997 Elsevier Science B.V.
