Abstract

We present a measurement of the WW+WZWW+WZ production cross section observed in a final state consisting of an identified electron or muon, two jets, and missing transverse energy. The measurement is carried out in a data sample corresponding to up to 4.6~fb1^{-1} of integrated luminosity at s=1.96\sqrt{s} = 1.96 TeV collected by the CDF II detector. Matrix element calculations are used to separate the diboson signal from the large backgrounds. The WW+WZWW+WZ cross section is measured to be 17.4±3.317.4\pm3.3~pb, in agreement with standard model predictions. A fit to the dijet invariant mass spectrum yields a compatible cross section measurement.
