Book excerpt: This thesis is a description of the measurement of the W boson mass using the D0 Run II detector with 770 pb−1 of p{bar p} collision data. These collisions were produced by the Tevatron at √s = 1.96 TeV between 2002 and 2006. We use a sample of W → e[nu] and Z → ee decays to determine the W boson mass with the transverse momentum distribution of the electron and the transverse mass distribution of the boson. We measure M{sub W} = XXXXX ± 37 (stat.) ± 26 (sys. theo.) ± 51 (sys. exp.) MeV = XXXXX ± 68 MeV with the transverse momentum distribution of the electron and M{sub W} = XXXXX ± 28 (stat.) ± 17 (sys. theo.) ± 51 (sys. exp.) MeV = XXXXX ± 61 MeV with the transverse mass distribution.
