Chris Hays, for the CDF, D0 Collaborations

The W boson mass (mW) is a key parameter of the standard model, constraining the mass of the unobserved Higgs boson. Using Tevatron ppbar collision data from 1992-1996, the CDF and D0 collaborations measured mW to a precision of 59 MeV. The ongoing Tevatron Run 2 has produced a factor of 5 more collisions, promising a significant reduction in the W mass uncertainty. CDF has analyzed the first 200/pb of Run 2 data and determined the uncertainty on its W mass measurement to be 76 MeV.
