Abstract

We update the measurement of the t (t) over bar production cross section using the CDF detector at the Fermilab Tevatron. This measurement uses t (t) over bar decays to the final states e + nu + jets and mu + nu + jets. We search for b quarks from t decays via secondary-vertex identification or the identification of semileptonic decays of the b and cascade c quarks. The background to the t (t) over bar production is determined primarily through a Monte Carlo simulation. However, we calibrate the simulation and evaluate its uncertainty using several independent data samples. For a top quark mass of 175 GeV/c(2), we measure sigma (t (t) over bar)-=5.1 +/- 1.5 pb and sigma (t (t) over bar)=9.2 +/- 4.3 pb using the secondary vertex and the lepton tagging algorithms, respectively. Finally, we combine these results with those from other t (t) over bar decay channels and obtain sigma (t (t) over bar)-= 6.5 (+1.7)(-1.4)pb
