Combination of CDF and D0 results on the mass of the top quark using up to 5.8~fb-1 of data
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 precise published and preliminary Run II (2001--present) measurements using up to 5.8 fb{sup -1} of data, adding new analyses (the missing transverse energy plus jets analysis) and updating old ones. Taking uncertainty correlations into account, and adding in quadrature the statistical and systematic uncertainties, the resulting preliminary Tevatron average mass of the top quark is M{sub t} = 173.2 {+-} 0.9 GeV/c{sup 2}.
