Book excerpt: This thesis describes a measurement of the W boson mass from a fit to the transverse momentum spectrum of the muon in W decay. In past measurements this technique was used as a cross-check, however, now presents the best method in terms of systematic uncertainty. We discuss all sources of systematic uncertainty with emphasis on those to which the muon p{sub T} measurement is particularly sensitive, specifically, those associated with modeling the production and decay of W bosons. The data were collected with the CDF II detector between March 2002 and September 2003 and correspond to an integrated luminosity of (191 ± 11) pb−1. We measure the W mass to be (80.316 ± 0.066{sub stat.} ± 0.051{sub syst.}) GeV/c2 = (80.316 ± 0.083) GeV/c2.
