Measurement of Di-boson Production in Electron Plus Jets Decays

We present a measurement of the simultaneous production of a W boson in association with a second electroweak boson (W of Z) in proton anti-proton collisions at $\sqrt{s} =$~1.96 TeV. We consider events with one electron, missing transverse energy, and at least two jets. Data used in this analysis consists of 1 fb$^{-1}$ of integrated luminosity collected by the D0 detector at the Tevatron.
