Combination of CDF and D0 Results on the W-Boson Width
The results on the direct measurements of the W-boson width, based on the data collected by the Tevatron experiments CDF and D0 at Fermilab during Run-I from 1992 to 1996 and Run-II since 2001 are summarized. The combination of the published Run-I and preliminary Run-II results, taking correlated uncertainties properly into account, is presented. The resulting preliminary Tevatron average for the total decay width of the W boson is: {Lambda}{sub W} = 2078 {+-} 87 MeV, where the total error consists of a statistical part of 62 MeV and a systematic part of 60 MeV.
