Abstract

We present a measurement of the W -boson-pair production cross section in p¯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 +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(p¯p → W +W −) = 14.0 ± 0.6 (stat)+1.2 −1.0 (syst) ± 0.8 (lumi) pb, consistent with the standard model prediction.
