Available in PDF, EPUB and Kindle. Book excerpt: We present a measurement of the W boson mass using 200 pb−1 of data collected in p{bar p} collisions at √s = 1.96 TeV by the CDF II detector at Run II of the Fermilab Tevatron. With a sample of 63964 W → ev candidates and 51128 W W → [mu]v candidates, we measure M{sub W} = (80413 ± 34{sub stat} ±34{sub syst} = 80413 ± 48) MeV/c2. This is the most precise single measurement of the W boson mass to date.
