First Measurement of the W Boson Mass in Run II of the Tevatron

Journal Article (Academic article)

We present a measurement of the W-boson mass using 200 pb-1 of data collected in p[overline p] collisions at sqrt(s)=1.96 TeV by the CDF II detector at run II of the Fermilab Tevatron. With a sample of 63 964 W-->enu candidates and 51 128 W-->µnu candidates, we measure MW=80 413$\pm$34stat$\pm$34syst=80 413$\pm$48 MeV/c2. This is the most precise single measurement of the W-boson mass to date.
