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 [Formula Presented] events recorded in an integrated luminosity of 84 [Formula Presented] gives a mass [Formula Presented] A fit to the transverse mass spectrum of a sample of 14740 [Formula Presented] events from 80 [Formula Presented] gives a mass [Formula Presented] The dominant contributions to the sys- tematic uncertainties are the uncertainties in the electron energy scale and the muon momentum scale, [Formula Presented] and [Formula Presented] respectively. The combined value for the electron and muon channel is [Formula Presented] When combined with previously published CDF measurements, we obtain [Formula Presented] © 2001 The American Physical Society.
