Title: W mass and width measurements at the Tevatron

Abstract

I present a measurement of the W boson mass (M{sub W}) and width ({Gamma}{sub W}) using 200 and 350 pb{sup -1} of CDF Run II data respectively. The measurements, performed in both the electron and muon decay channels, rely on a fit to the W transverse mass distribution. We measure M{sub W} = 80413 {+-} 48 MeV and {Gamma}W = 2032 {+-} 71 MeV which represent the world's single most precise measurements to date.
