Abstract:
We present a measurement of the \ttbar production cross section using 194pb1194 \mathrm{pb^{-1}} of CDF II data using events with a high transverse momentum electron or muon, three or more jets, and missing transverse energy. The measurement assumes 100% tWbt\to Wb branching fraction. Events consistent with \ttbar decay are found by identifying jets containing heavy flavor semileptonic decays to muons. The dominant backgrounds are evaluated directly from the data. Based on 20 candidate events and an expected background of 9.5±\pm1.1 events, we measure a production cross section of 5.3±3.31.0+1.3pb5.3\pm3.3^{+1.3}_{-1.0} \mathrm{pb}, in agreement with the standard model.
