摘要

\We present a measurement of the W boson mass using data collected by the DO experiment at the Fermilab Tevatron during 1994-1995. We identify W bosons by their decays to ev final states where the electron is detected in a forward calorimeter. We extract the W boson mass M-W by fitting the transverse mass and transverse electron and neutrino momentum spectra from a sample of 11 089 W-->e nu decay candidates. We use a sample of 1687 dielectron events, mostly due to Z-->ee decays, to constrain our model of the detector response. Using the forward calorimeter data, we measure M-w=80.691+/-0.227 GeV. Combining the forward calorimeter measurements with our previously published central calorimeter results, we obtain M-W= 80.482 +/-0.091 GeV.
