Summary of Tevatron Top Mass Results - March 2013

Summary of the Tevatron top mass measurements and their combination as of March 2013. We combine published results from Run-I (1992-1996) with the most recent preliminary and published Run-II (2001-present) measurements using up to 8.7 fb-1 of data. Taking correlated uncertainties properly into account the resulting preliminary Tevatron average mass of the top quark is

Mtop = 173.20 ± 0.51 (stat) ± 0.71 (syst) GeV/c2

or summing the statistical and systematical uncertainties in quadrature

Mtop = 173.2 ± 0.9 (syst) GeV/c2
which corresponds to a relative uncertainty of 0.50%.

More information about the combination methos can be found in PRD 86 092003 . and for the current result in CDF Note 10976 .

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