Abstract

We summarize the published top-quark mass measurements from the CDF and DO experiments at Fermilab. We combine published Run-I (1992-1996) measurements with the most recent published Run-II (2001-present) measurements using up to 340 pb of data. Taking correlated uncertainties properly into account the resulting mass of the top quark is m(top)=174.2 +- 2.0(stat) +- 2.6(syst) GeV/c2, which corresponds to a total uncertainty of 3.3 GeV/c2, i.e. 1.9% precision. Since this combination uses only a subset of the available analyses and data sets, it does not supersede our latest world average combination of m(top)=172.5 +- 1.3(stat) +- 1.9(syst) GeV/c2, which is based on the latest published and preliminary results.
