Diboson Production at D 0

We present recent diboson production measurements from the D0 experiment at Fermilab's Teva-tron collider. The production of ZZ was observed using leptonic final states. Zγ → ννγ was observed and used to set the most stringent limits from a hadron collider on anomalous Zγγ and ZZγ trilinear gauge couplings (TGCs). WW events with leptonic final states and WW +W Z events with semi-leptonic final states were used to set limits on anomalous WW Z and WW γ TGCs. Finally , limits on anomalous WW Z and WW γ TGCs were obtained from a combination of the fully-leptonic W γ, WW , and W Z channels and the semi-leptonic WW and W Z channels, giving the most stringent limits from a hadron collider.
