W boson mass measurement at the Tevatron

OSTI ID:15017172
The W boson mass (m{sub w}) is a key parameter of the standard model (SM), constraining the mass of the unobserved Higgs boson. Using Tevatron p{bar p} collision data from 1992-1995, the CDF and D0 collaborations measured m{sub w} to {delta}m{sub w} = 59 MeV. The ongoing Tevatron Run 2 has produced a factor of 5 more collisions, promising a significant reduction in {delta}m{sub w}. CDF has analyzed the first {approx}200 pb{sup -1} of Run 2 data and determined its {delta}m{sub w} to be 76 MeV.
