Electroweak precision measurements performed by CDF and DØ are reported, corresponding to data col- lected at the center-of-mass energy of 1.96 TeV with the integrated luminosity ranging from 0.75 fb^−1 to 4.9 fb^−1 . These include the measurement of the W boson charge asymmetry, the measurement of the Z boson rapidity distribution, the measurement of the Z boson p_T distri- bution, and direct measurement of the W boson mass and width.

The W mass is a crucial parameter in the Standard Model (SM) of particle physics, providing constraints on the mass of the Higgs boson as well as on new physics models via quantum loop corrections. On the other hand, any deviation of the triple gauge boson couplings (TGC) from their values predicted by the SM would be also an indication for new physics. We present recent measurements on W boson mass and searches for anomalous TGC (aTGC) in Wγ, Zγ, WW, WZ and ZZ at Fermilab Tevatron both by CDF and DØ Collaborations. The CDF Collaboration has measured the W boson mass using data corresponding to 2.2 fb−1 of integrated luminosity. The measurement, performed using electron and muon decays of W boson, yields a mass of MW = 80387 ± 19 MeV. The DØ Collaboration has measured MW = 80367 ± 26 MeV with data corresponding to 4.3 fb−1 of integrate...
Electroweak measurements performed by CDF and D0 are reported, corresponding to data collected at the centre-of-mass energy of 1.96 TeV with approximately a luminosity of $200pb^-1$. We present measurements of W and Z cross sections and decay asymmetries, recent results in diboson physics with new limits on anomalous couplings, preliminary results on the direct determination of the W width, and preliminary studies for the W mass measurement.
