Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes a direct measurement of the W boson total decay width, ?W, using the D0 detector at the Fermilab Tevatron Collider. The measurement uses an integrated luminosity of 177.3 pb-1 data, collected during the 2002-2003 run. The width is determined from the shape of the transverse mass distribution, MT, by fitting the data in the tail region 100 MsubT/sub 200 GeV. The result if ?
