Description

We present the most precise single measurement of the W boson mass and and a measurement of the W width using data collected with the D0 experiment. An integrated luminosity of 1 fb-1 yields 499,830 W->evcandidates. The mass is measured with an uncertainty of less than 45 MeV while the width uncertainty is less than 75 MeV.
