Electroweak Physics [W/Z]
We present high statistics measurements of diboson production in ppbar
collisions at the D0 experiment in multiple channels, including
WW -> lvlv, WW/Z-> lvjj and WZ->lvll. These measurements both test
physics beyond the standard model and demonstrate the sensitivity of
hadron colliders to rare signals such as Higgs boson production.

Electroweak Physics [W/Z]
We present the first observation of the Zgamma to nunugamma process at the Tevatron at 5.1 standard deviations significance, based on 3.6 fb-1 of integrated luminosity collected with the D0 detector at the Fermilab Tevatron ppbar Collider at sqrt{s} = 1.96 TeV. The measured Zgamma cross section multiplied by the branching fraction of Z to nunu is 32 +- 9 (stat.+syst.) +- 2 (lumi.) fb for the...

Electroweak Physics [W/Z]
We present a search for WW plus WZ production in the lepton plus missing transverse energy plus two jets channel at CDF. A matrix element technique is employed to separate the signal from the large W plus jets background. The WW plus WZ production cross section is measured and compared against the standard model NLO prediction.

Electroweak Physics [W/Z]
We present the first observation in hadronic collisions of the electroweak production of vector boson pairs (VV, V=W,Z) where one boson decays to a dijet final state. The data correspond to 3.5 fb^-1 of integrated luminosity of p-pbar collisions at sqrt(s)=1.96 TeV collected by the CDF II detector at the Fermilab Tevatron. Event selection requires two jets and large transverse momentum...

Electroweak Physics [W/Z]
We present the latest results on the production of WW, WZ, W gamma, Z gamma
and ZZ events at the Fermilab Tevatron Collider. The results are based on the analyses
of a few fb^-1 of data collected in p pbar collisions at center of mass energy of 1.96TeV
by CDF and DO experiments during the Tevatron RunII. Analyses of the diboson production
processes provide crucial test of the Standard...
