Measurement of the W boson mass

PDF Version Also Available for Download.

Description

We present a preliminary measurement of the {ital W} boson mass using data collected by the D{null} experiment at the Fermilab Tevatron during the 1994-1995 collider run 1b. We use {ital W} {r_arrow} {ital e}{nu} decays to extract the {ital W} mass from the observed spectrum of transverse mass of the electron ({vert_bar}{eta}{vert_bar} {lt} 1. 2) and the inferred neutrino We use {ital Z}{sup 0} {r_arrow} {ital ee} decays to constrain our model of the detector response. We measure {ital m}{sub W}/{ital m}{sub Z} = 0.8815 {+-} 0.0011({ital stat}) {+-} 0.0014({ital syst}) and {ital m}{sub W} = 80.38 {+-} 0.07 ... continued below

Combining this result with our previous measurement from the 1992-1993 data, we obtain {ital m}{sub W} = 80.37 {+-} 0.15 GeV (errors combined in quadrature).
