    Abstract:
    We present a measurement of the W boson mass using data collected by the D0 experiment at the Fermilab Tevatron during 1994-1995. We identify W bosons by their decays to ev final states. We extract the W mass MW by fitting the transverse mass and transverse electron momentum spectra from a sample of 28 323 W → ev decay candidates. We use a sample of 3563 dielectron events, mostly due to Z → ee decays, to constrain our model of the detector response. From the transverse mass fit we measure MW = 80.44±0.10(stat)±0.07(syst) GeV. Combining this with our previously published result from data taken in 1992-1993, we obtain MW = 80.43±0.11 GeV.
