Measurement of the W boson mass

  • 1. Columbia Univ., New York, NY (United States). Dept. of Physics

Description

We present a preliminary measurement of the W boson mass using data collected by the D null experiment at the Fermilab Tevatron during the 1994-1995 collider run 1b. We use W → eν decays to extract the W mass from the observed spectrum of transverse mass of the electron (|η| < 1. 2) and the inferred neutrino We use Z0 → ee decays to constrain our model of the detector response. We measure mW/mZ = 0.8815 ± 0.0011(stat) ± 0.0014(syst) and mW = 80.38 ± 0.07 (W stat) ± 0.13(syst) GeV. Combining this result with our previous measurement from the 1992-1993 data, we obtain mW = 80.37 ± 0.15 GeV (errors combined in quadrature)
