Abstract

We present a measurement of the mass of the

W

boson using data collected with the Collider Detector at Fermilab during the 1992–93 collider run at the Fermilab Tevatron. A fit to the transverse mass spectrum of a sample of 3268

W \to μ ν

events recorded in an integrated luminosity of

19.7 {pb}^{- 1}

gives a mass

M_{W}^{μ} = 80.310 \pm 0.205 (stat) \pm 0.130 (syst) GeV {/ c}^{2}

. A fit to 5718

W \to e ν

events recorded in 18.2 p

b^{- 1}

gives

M_{W}^{e} = 80.490 \pm 0.145 (stat) \pm 0.175 (syst) GeV {/ c}^{2}

. Combining these results, accounting for correlated uncertainties, yields

M_{W} = 80.410 \pm 0.180 GeV {/ c}^{2}
