ABSTRACT

We present a measurement of the W boson mass using data corresponding to 4.3fb-1 of integrated luminosity collected with the D0 detector during Run II at the Fermilab Tevatron ppbar collider. With a sample of 1,677,394 W-goes-to-enu candidate events, we measure MW = 80.367+-0.026 GeV. This result is combined with an earlier D0 result determined using an independent Run II data sample, corresponding to 1fb-1 of integrated luminosity, to yield MW = 80.375+-0.023 GeV.
