The mass of the W boson is sensitive to radiative corrections from the top quark and the Higgs boson. We present a new measurement of mW using 2.2/fb of sqrt(s)=1.96 TeV ppbar collision data collected with the CDF II detector. Utilizing 470126 W → eν candidates and 624708 W → μν candidates, we measure mW = 80387±19 MeV. This is the most precise measurement of mW, more precise than all previous measurements of mW combined.
