Measurement of the W boson mass with the D0 Run II detector using the electron transverse momentum spectrum

This thesis is a description of the measurement of the W boson mass using the D0 Run II detector with 770 pb-1 of pp¯ collision data. These collisions were produced by the Tevatron at s = 1.96 TeV between 2002 and 2006. We use a sample of W → enu 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 MW = 80340 +/- 37 (stat.) +/- 26 (sys. theo.) +/- 51 (sys. exp.) MeV = 80340 +/- 68 MeV with the transverse momentum distribution of the electron and MW = 80361 +/- 28 (stat.) +/- 17 (sys. theo.) +/- 51 (sys. exp.) MeV = 80361 +/- 61 MeV with the transverse mass distribution.
