A measurement of the top pair production cross section in the dimuon final state for proton-antiproton collisions at s**(1/2) = 1.96 TeV is presented. Approximately 420 pb^{-1} of data collected with the Run II D0 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: 3.13 {+4.17} {-2.60} (stat) {+0.92} {-0.86} (sys) +/- 0.19 (lumi) pb, which is consistent with a NNLO prediction of 6.77 +/- 0.42 pb.Type
