Summary of Tevatron Top Mass Results - July 2010

Summary of the Tevatron top mass measurements and their combination as of July 2010. We combine published results from Run-I (1992-1996) with the most recent preliminary and published Run-II (2001-present) measurements using up to 5.6 fb-1 of data. Taking correlated uncertainties properly into account the resulting preliminary Tevatron average mass of the top quark is

Mtop = 173.3 ± 0.6 (stat) ± 0.9 (syst) GeV/c2

which corresponds to a total uncertainty of 1.1 GeV/c2.
