【 摘 要 】

We summarize and combine direct measurements of the width of the W boson in data collected by the Tevatron experiments CDF and D0 at Fermilab. Results from CDF and D0 Run-I (1992-1995) have been combined with the CDF 200 pb{sup -1} results from the first period of Run-II (2001-2004) and the recent 1 fb{sup -1} result in the electron channel from D0 (2002-2006). The results are corrected for any inconsistencies in parton distribution functions and assumptions about electroweak parameters used in the different analyses. The resulting Tevatron average for the width of the W boson is {Lambda}{sub W} = 2,046 {+-} 49 MeV.
