Measurement of the W Boson Mass with the D0 Detector

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 p\bar{p} collider. With a sample of $1,677,394$ W -> e\nu candidate events, we measure M_W = 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 M_W = 80.375 +- 0.023 GeV.
