We present a measurement of the W-boson-pair production cross section in p (p) over bar 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 sigma(p (p) over bar --> W+W-) = 14.0 +/- 0.6(stat)(-1.0)(+1.2)(syst) +/- 0.8(lumi) pb, consistent with the standard model prediction.
