dc.description.abstract | We report two complementary measurements of the WW+WZ cross section in the final state consisting of an electron or muon, missing transverse energy, and jets, performed using pp̅ collision data at √s=1.96 TeV collected by the CDF II detector. The first method uses the dijet invariant mass distribution while the second more sensitive method uses matrix-element calculations. The result from the second method has a signal significance of 5.4σ and is the first observation of WW+WZ production using this signature. Combining the results gives σWW+WZ=16.0±3.3 pb, in agreement with the standard model prediction. | es_ES |
