Abstract
We present a measurement of the W boson mass in W → ev decays using 1 fb-1 of data collected with the D0 detector during Run II of the Fermilab Tevatron collider. With a sample of 499830 W → ev candidate events, we measure MW = 80.401 ± 0.043 GeV. This is the most precise measurement from a single experiment.
