Abstract
We present a measurement of the W-boson-pair production cross section in p[bar over p] collisions at 1.96 TeV center-of-mass energy and the first measurement of the differential cross section as a function of jet multiplicity and leading-jet energy. The W[superscript +]W[superscript -] cross section is measured in the final state comprising two charged leptons and neutrinos, where either charged lepton can be an electron or a muon. Using data collected by the CDF experiment corresponding to 9.7 fb[superscript -1] of integrated luminosity, a total of 3027 collision events consistent with W[superscript +]W[superscript -] production are observed with an estimated background contribution of 1790 ± 190 events. The measured total cross section is σ(p[bar over p] → W[superscript +]W[superscript -]) = 14.0 ± 0.6(stat)[+1.2 over -1.0](syst) ± 0.8(lumi) pb, consistent with the standard model prediction.
