Abstract

The central value and theoretical uncertainties on the cross section ratio sigma_W/sigma_Z at the Tevatron are evaluated using the NNLO calculations and the latest MSTW PDFs. The partial width, total width and branching ratios of the W boson in the Standard Model, in the light of the latest electroweak calculations, are also updated.
