First run II measurement of the W boson mass at the Fermilab Tevatron

We describe a measurement of the W boson mass mW using 200pb-1 of s=1.96TeV pp̄ collision data taken with the CDF II detector. With a sample of 63964 W→eν candidates and 51128 W→μν candidates, we measure mW=[80.413±0.034(stat)±0.034(sys)=80.413±0.048]GeV/c2. This is the single most precise mW measur...
