Book Description
With a large and still increasing dataset, W and Z boson physics studies at the Tevatron p{bar p} collider are particularly useful for testing many aspects of the Standard Model. In this proceeding, we present measurements of electroweak boson properties, distributions, and charge asymmetries. We examine both solitary W and Z production as well as production in association with jets. These measurements are compared to NLO QCD predictions, are used to extract fundamental Standard Model parameters, and constrain parton distribution functions.

Book Description
Using data collected from p{anti p} collisions at the Fermilab Tevatron collider the latest electroweak results from the CDF and D0 collaborations are presented. Measurements of the W and Z boson production cross sections are detailed, which in addition to testing the Standard Model in their own right also allow a determination of the W boson width. Analyses of Drell-Yan production above the Z pole allow limits to be placed on the existence of neutral gauge bosons beyond the Standard Model and parton compositeness. A first measurement of the forward backward asymmetry of the Drell-Yan lepton pairs above the Z pole is also presented. The latest measurements from both collaborations of the W mass are described, which when averaged yield a W mass value of 80.375 " 0.100 GeV/c2.

Book Description
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.

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
We summarize an extensive Tevatron (1984-2011) electroweak physics program that involves a variety of W and Z boson precision measurements. The relevance of these studies using single and associated gauge boson production to our understanding of the electroweak sector, quantum chromodynamics and searches for new physics is emphasized. Furthermore, we discuss the importance of the W boson mass measurement, the W/Z boson distributions and asymmetries, and diboson studies. We also highlight the recent Tevatron measurements and prospects for the final Tevatron measurements.

Book Description
W and Z bosons are mainly produced via quark-antiquark annihilations at the Fermilab Tevatron collider. Precision measurements with these gauge bosons provide us with high precision tests of the Standard Model (SM) as well as indirect search for possible new physics beyond the SM. I present the recent electroweak measurements related to single W, Z boson and diboson productions from the CDF and D0 experiments at the Fermilab Tevatron collider.

Book Description
The two detectors at the Fermilab Tevatron, D0 and CDF, have collected large samples of W and Z decays. With these data measurements of the properties of the W boson have been performed. From the ratio of the W and Z production cross sections a measurement of the W boson width of 2.062 " 0.059 GeV has been obtained. The W boson mass has been measured to be 80.34 " 0.15 GeV. Both detectors have observed diboson production and measured the triple gauge boson couplings. No deviations from Standard Model predictions have been observed.

Book Description
The CDF and D0 experiments at the Tevatron have used p{bar p} collisions at {radical}s = 1.96 TeV to perform electroweak physics measurements. A program of precision electroweak tests of SM already started. Measurements performed are: W and Z bosons production cross section using different leptonic final states, dielectron Forward-Backward Asymmetry A{sub FB} and di-boson cross section production. We also report the prospects for the W mass measurements.

Book Description
Preliminary electroweak results are discussed from the Fermilab experiments, CDF and DO, based on Tevatron run 1b data. These include an updated precision measurement of the W mass which when combined with previous Tevatron, CERN S[bar p]S, and LEP-II results gives a combined world average M[sub W]= 80.40[+-] 0.08 GeV/c[sup 2]. Also presented are new limits on anomalous gauge boson self-couplings, measurement of the W charge asymmetry, [sigma][center-dot]B(W[yields][tau][nu][sub[tau]]), and limits on quark/lepton compositeness from high mass Drell-Yan production.
