【 摘 要 】

The W boson mass (m(sub w)) is a key paramter of the standard model (SM), containing the mass of the unobserved Higgs boson. Using Tevatron p(bar p) collison data from 1992-1995, the CDF and D0 collaborations measured m(sub w) to m(sub w) = 59 MeV. The ongoing Tevatron Run 2 has produced a factor of 5 more collisions, promising a significant reduction in m(sup w). CDF has analyzed the first approximately (nearly) equal to 200 pb(sub -1) of Run 2 data and determined its m(sup w) to be 76 MeV.
