摘要
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→μν events recorded in an integrated luminosity of 19.7 pb-1 gives a mass MWμ=80.310±0.205(stat)±0.130(syst) GeV/c2. A fit to 5718 W→eν events recorded in 18.2 pb-1 gives MWe=80.490±0.145(stat) ±0.175syst GeV/c2. Combining these results, accounting for correlated uncertainties, yields MW=80.410±0.180 GeV/c2. © 1995 The American Physical Society.
