Determination of the mass of the $$W$$ boson using the D\O\ detector at the Tevatron
A measurement of the mass of the W boson is presented which is based on a sample of 5982 W -> e nu decays observed in pbar-p collisions at sqrt(s) = 1.8 TeV with the D0 detector during the 1992-1993 run. From a fit to the transverse mass spectrum, combined with measurements of the Z boson mass, the W boson mass is measured to be M_W = 80.350+-0.140(stat)+-0.165(sys)+-0.160(scale) GeV/c^2. Detailed discussions of the determination of the absolute energy scale, the measured efficiencies, and all systematic uncertainties are presented.
