Measurement of the production and differential cross sections of W+W- bosons in association with jets in p¯p collisions at vs=1.96??TeV

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 s(p¯p?W+W-)=14.0±0.6(stat)+1.2-1.0(syst)±0.8(lumi)??pb, consistent with the standard model prediction.
