Abstract
We present a measurement of the W boson mass using data collected with the CDF detector during the 1994–1995 collider run at the Fermilab Tevatron. A fit to the transverse mass spectrum of a sample of 30115 W→eν events recorded in an integrated luminosity of 84 pb-1 gives mass MW=80.473±0.065(stat)±0.092(syst) GeV/c2. A fit to the transverse mass spectrum of a sample of 14740 W→μν events from 80 pb-1 gives a mass MW=80.465±0.100(stat)±0.103(syst) GeV/c2. The dominant contributions to the sys- tematic uncertainties are the uncertainties in the electron energy scale and the muon momentum scale, 0.075 GeV/c2 and 0.085 GeV/c2, respectively. The combined value for the electron and muon channel is MW=80.470±0.089 GeV/c2. When combined with previously published CDF measurements, we obtain MW=80.433±0.079 GeV/c2.
