Measurement of the<i>W</i>boson mass

Measurement of the<i>W</i>boson mass

We present a measurement of the W boson mass using data collected by the D0 experiment at the Fermilab Tevatron during 1994–1995. We identify W bosons by their decays to eν final states. We extract the W mass MW by fitting the transverse mass and transverse electron momentum spectra from …
