213. High Statistics Measurement of Di-boson Production with the D0 Detector

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.

212. Measurements of the Trilinear Gauge Boson Couplings from Diboson Production at D0

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...

310. Search for diboson production in final states with one lepton, missing transverse energy, and jets at CDF

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.

350. First Observation of Diboson Production in Hadronic Final State at Tevatron

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...

435. Diboson physics at Tevatron

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...
