Summary of Tevatron Top Mass Results - July 2008

Summary of the Tevatron top mass measurements and their combination as of July 2008. We combine published results from Run-I (1992-1996) with the most recent preliminary and published Run-II (2001-present) measurements using up to 2.8 fb-1 of data. Taking correlated uncertainties properly into account the resulting preliminary CDF average mass of the top quark is

Mtop = 172.4 ± 0.7 (stat) ± 1.0 (syst) GeV/c2

which corresponds to a total uncertainty of 1.2 GeV/c2.

More information can be found in hep-ex/0808.1089.

References about the individual analyses contributing to this combination can be found from the CDF public page and D0 public page.
