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<MT<200 GeV. The result is Gamma_{W}=2.011 +- 0.093 (stat) +- 0.107 (syst) GeV. 2607101 bytes application/pdf en_US Direct Measurement of the W Boson Decay Width in Proton-Antiproton Collisions at sqrt(s)=1.96 TeV Dissertation Physics, Elementary Particles and High Energy Electroweak W Width Transverse Mass Direct Measurement open.access
