Book Description
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}.

Book Description
Direct measurements of the trilinear gauge boson couplings by the CDF and D0 collaborations at Fermilab are reviewed. Limits on the anomalous couplings were obtained at a 95% CL from four diboson production processes: W[gamma] production with the subsequent W boson decay to e[nu] or[mu][nu], WW production with both the W boson decaying to e[nu] or[mu][nu], WW/WZ production with one of the gauge bosons decaying leptonically and the other gauge boson decaying to two jets, and Z[gamma] production with the subsequent Z boson decay to ee, [mu][mu], or[nu][nu]. Limits were also obtained by a combined fit to W[gamma], WW[yields]dileptons and WW/WZ semileptonic data samples.

Book Description
Results from the CDF and D{O} experiments are presented on properties of the W" and Z° gauge bosons using final states containing electrons and muons based on large integrated luminosities. In particular, measurements of the W" and Z° production cross sections, the W-charge asymmetry and the CDF measurement of the W-mass are summarized. Gauge boson self interactions axe measured by studying di-gauge boson production and limits on anomalous gauge boson couplings axe discussed.

Book Description
The discovery reach of the Tevatron in the 1990's for new gauge bosons which originate in a wide range of extensions to the Standard Model is obtained. Most searches make use of the conventional leptonic decay mode of the Z(prime), whereas others require the observation of a dijet mass peak above the QCD background from hadronic decays. 10 refs., 3 figs.

Book Description
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.

Book Description
This report summarizes recent measurements of the production properties of WW and WZ pairs of bosons at the Tevatron. This includes measurements of the cross-section and triple gauge couplings in the WW process and the first evidence for WZ production.

Book Description
Preliminary results from the DO experiment are presented on production properties of the W[sup [plus-minus]] and Z[sup 0] gauge bosons using final states containing electrons and muons. The DO detector has accumulated 16.7 pb[sup [minus]1] of data at the Fermilab [bar p]p Tevatron collider. Based on a subset of this data preliminary measurements of the W[sup [plus-minus]] and Z[sup 0] production cross section and a measurement of [alpha][sub s] at Q[sup 2] = M[sub W][sup 2] derived from the ratio of W + 1jet to W + 0jets is presented.
