Abstract

WWe present a measurement of the W-boson mass using 200 pb−1 of data collected in pp collisions at s√=1.96 TeV by the CDF II detector at run II of the Fermilab Tevatron. With a sample of 63 964 W→eν candidates and 51 128 W→μν candidates, we measure MW=80 413±34stat±34syst=80 413±48 MeV/c2. This is the most precise single measurement of the W-boson mass to date.
