Summary:

The CDF and D0 collaborations have analyzed up to ≈ 200 pb⁻¹ of Run 2 physics data to measure W production properties such as the W cross section, the W width, lepton universality and the W charge asymmetry. From the cross section measurements, CDF obtains a lepton universality of g{sub μ}/g{sub e} = 0.998 ± 0.012 and g{sub τ}/g{sub e} = 0.99 ± 0.04 and an indirect W width of Λ{sub W} = 2079 ± 41 MeV. D0 measured the W width directly and finds Λ{sub W} = 2011 ± 142 MeV. CDF has estimated the uncertainties on the W boson mass measurements in the electron and muon decay channels and obtains an overall uncertainty of 76 MeV.
