Combination of CDF and D0 Results on the Width of the W boson

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 RunI (1992-1995) have been combined with the CDF 200 pb^-1 results from the first period of RunII (2001-2004) and the recent 1 fb^-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 Gamma_W = 2,046 +- 49.

Updated Combination of CDF and D0 Results for the Mass of the W Boson

We summarize and combine the results on the direct measurements of the mass of the W boson in data collected by the Tevatron experiments CDF and D0 at Fermilab. Results from CDF Run-0 (1988-1889) and Run-I (1992-1995) have been combined with D0 results from Run-I, the CDF 200 pb^(-1) published results from the first period of Run-II (2001-2004) and the recent 1 fb^(-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 mass of the W boson is M(W) = 80,420+31 MeV.

Combination of CDF and D0 Results on the Mass of the Top Quark

We summarize the top-quark mass measurements from the CDF and D0 experiments at Fermilab. We combine published Run-I (1992-1996) measurements with the most recent preliminary Run-II (2001-present) measurements using up to 2.8 fb^-1 of data. Taking correlated uncertainties properly into account the resulting preliminary world average mass of the top quark is M_t = 172.4 +/- 0.7 (stat.) +/- 1.0 (syst.) GeV/c^2, assuming Gaussian systematic uncertainties. Adding in quadrature yields a total uncertainty of 1.2 GeV/c^2, corresponding to a relative precision of 0.7% on the top-quark mass.

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 DØat Fermilab during {\RunI} from 1992 to 1996 and {\RunII} since 2001 are summarized. The combination of the published {\RunI} and preliminary {\RunII} results, taking correlated uncertainties properly into account, is presented. The resulting preliminary Tevatron average for the total decay width of the W boson is: $\GW=2078\pm87 \MeV$, where the total error consists of a statistical part of $62 \MeV$ and a systematic part of $60 \MeV$.
