Diboson Production at D0

We present recent diboson production measurements from the D0 experiment at Fermilab's Tevatron collider. The production of ZZ was observed using leptonic final states. Zgamma->nunugamma was observed and used to set the most stringent limits from a hadron collider on anomalous Zgammagamma and ZZgamma trilinear gauge couplings (TGCs). WW events with leptonic final states and WW+WZ events with semi-leptonic final states were used to set limits on anomalous WWZ and WWgamma TGCs. Finally, limits on anomalous WWZ and WWgamma TGCs were obtained from a combination of the fully-leptonic Wgamma, WW, and WZ channels and the semi-leptonic WW and WZ channels, giving the most stringent limits from a hadron collider.

First Evidence of WW/WZ -> lnuqq at the Tevatron

We present the first evidence from a hadron collider of WW+WZ production with semi-leptonic decays. The data were recorded by the D0 detector at the Fermilab Tevatron and correspond to 1.07 inverse femtobarn of integrated luminosity obtained in proton-antiproton collisions at sqrt(s) = 1.96 TeV. The cross section observed for WW+WZ production is 20.2 +- 4.5 pb with a significance of 4.4 standard deviations.
