The authors present some precision measurements on electroweak physics performed at the Tevatron collider at Fermilab. Namely they report on the boson-pair production cross sections and on triple gauge boson couplings using proton anti-proton collisions collected by the CDF and D0 experiments at the center-of-mass energy of 1.96 TeV. The data correspond to an integrated luminosity of up to 324 pb{sup -1}.

Tremendous progress has been made in recent years in the measurement of heavy boson pair-production at the Tevatron collider. I will briefly review the current status of heavy diboson production measurements at CDF and D0 with special emphasis on the recently released ZZ cross section measurements.

A summary is presented of recent measurements of di-boson production at the Tevatron. The results from the CDF and D0 experiments are based upon 130-320 pb{sup -1} of p{bar p} collisions at {radical}s = 1.96 TeV. The W{gamma}, Z{gamma}, WW, and WZ production properties are compared to Standard Model predictions, and limits extracted for anomalous triple gauge couplings.

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 hadronic final state. The data correspond to 3.5 fb−1 of integrated luminosity collected by the CDF II detector in p{bar p} collisions at a center-of-mass energy of 1.96 TeV. Event selection requires two identified jets and large transverse momentum imbalance. The analysis employs several novel techniques to suppress multijet background and reduce systematic uncertainties. We observe 1516 ± 239(stat) ± 144(syst) diboson candidate events and measure a cross section of [sigma](p{bar p} 2!VV + X) = 18.0 ± 2.8(stat) ± 2.4(syst) ± 1.1(lumi) pb, in agreement with standard model (SM) expectations.

At the Fermilab Tevatron, the CDF and D0 detectors are being used to study diboson production in p{bar p} collisions at {radical}s = 1.96 TeV. The authors summarize recent measurements of the W{gamma}, Z{gamma}, and WW cross-sections and limits on WZ and ZZ production. Limits on anomalous trilinear gauge couplings are also presented.

The discovery of the Higgs boson would be a major success for the Standard Model (SM) and would provide further insights into the electroweak symmetry breaking mechanism. This report contains the latest results from the D0 and CDF Tevatron experiments on searches for the SM Higgs produced from gluon fusion with H {yields} WW, and in association with a W boson. It also includes searches for a supersymmetric Higgs in the b{bar b} and {tau}{sup +}{tau}{sup -} decay channels. The study of di-boson production at the Tevatron is important to understand backgrounds in high mass Higgs searches. It also provides a test of the SM through the measurement of the production cross section and the gauge boson self couplings. This paper includes measurements of the WW, W{gamma}, and WZ production cross sections, as well as limits on the anomalous couplings associated with the WW{gamma} and WWZ interactions. The results are based on sets of up to 320 pb{sup -1} of data collected by the D0 and CDF experiments at the {bar p}p Tevatron collider, running at a center-of-mass energy of 1.96 TeV.

The studies of the diboson production in p{bar p} collisions at 1.96 TeV performed by CDF and D0 collaborations at the Tevatron collider are reported in this paper. The diboson events are identified by means of both leptonic and semi-leptonic final states. The presented results use different statistical samples collected by the Tevatron up to 4.8 fb−1. Measured production cross sections are in good agreement with Standard Model predictions and the limits on the anomalous triple gauge boson couplings are competitive with those measured by experiments at the Large Electron-Positron collider (LEP).

Recent measurements of processes involving the electroweak bosons, Z and W, performed at the Fermilab Tevatron Collider are summarized. The large integrated luminosities collected by both the D0 and CDF Collaborations enable precise measurements of differential single boson production cross sections, the determination of the W mass with unprecedented precision, and the observation of diboson production including ZZ.
