In this study, we present a measurement of the W-boson-pair production cross section in pp¯ 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+W 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–1 of integrated luminosity, a total of 3027 collision events consistent with W+W– production are observed with an estimated background contribution of 1790±190 events. The measured total cross section is σ(pp¯→W+W) = 14.0 ± 0.6(stat)+1.2–1.0 (syst)±0.8 (lumi) pb, consistent with the standard model prediction.
