OSTI ID:940087
We report an updated measurement of the top quark mass obtained from ppbar collisions at sqrt(s) = 1.96 TeV at the Fermilab Tevatron using the CDF II detector. Our measurement uses a matrix element integration method to obtain a signal likelihood, with a neural network used to identify background events and a likelihood cut applied to reduce the effect of badly reconstructed events. We use a 2.7 fb{sup -1} sample and observe 422 events passing all of our cuts. We find m{sub t} = 172.2 +/- 1.0 (stat.) +/- 0.9 (JES) +/- 1.0 (syst.) GeV/c{sup 2}, or m{sub t} = 172.2 +/- 1.7 (total) GeV/c{sup 2}.
