| A measurement of the top pair production cross section in the dimuon final state for proton-antiproton collisions at s = 1:96 TeV is presented. Approximately 420 pb-1 of data collected with the Run II DO detector are used for this measurement. Two data events are observed with a total expected signal plus background yield of 3.6 events. Assuming a top mass of 175 GeV, the measured cross section is: stt&d1;=3.13 +4.17-2.60stat +0.92-0.86sys +/-0.19lumipb, 1 which is consistent with a NNLO prediction of 6.77 +/- 0.42 pb. |
