| We present a measurement of the top quark pair production cross section in pp̅ collisions at √s=1.96 TeV using 318 pb-1 of data collected with the Collider Detector at Fermilab. We select tt̅ decays into the final states eν+jets and μν+jets, in which at least one b quark from the t-quark decays is identified using a secondary vertex-finding algorithm. Assuming a top quark mass of 178 GeV/c2, we measure a cross section of 8.7±0.9(stat)-0.9+1.1(syst) pb. We also report the first observation of tt̅ with significance greater than 5σ in the subsample in which both b quarks are identified, corresponding to a cross section of 10.1-1.4+1.6(stat)-1.3+2.0(syst) pb. | |
