This dissertation measures the t{bar t} production cross section at the Run II CDF detector using data from early 2001 through March 2007. The Tevatron at Fermilab is a p{bar p} collider with center of mass energy √s = 1.96 TeV. This data composes a sample with a time-integrated luminosity measured at 2.2 ± 0.1 fb−1. A system of learning machines is developed to recognize t{bar t} events in the 'lepton plus jets' decay channel. Support Vector Machines are described, and their ability to cope with a multi-class discrimination problem is provided. The t{bar t} production cross section is then measured in this framework, and found to be [sigma]{sub t{bar t}} = 7.14 ± 0.25 (stat){sub -0.86}{sup +0.61}(sys) pb.

We report on the measurement of the t[anti t] production cross section obtained by CDF and D0 experiments with p[anti p] collisions at[radical]s=1. 8 TeV. The analyses presented here refer to[integral] Ldt[approx]11O pb[sup -1] collected at the Fermilab Tevatron collider during the run 1992-96. About 85% of the possible t[anti t] decays have been studied in different channels classified according to the number of high P[sub T] leptons found in the final state. The production cross section has been measured in each individual channel and then combined into a single value for each experiment, which is[sigma][sub tt]= 7.5[sup 1.9][sub 1.6] pb for CDF and[sigma][sub tt]= 5.77[+-] 1.76 pb for D0.

We report on the results from the analyses of[ital t][ital[anti t]] decays in[ital dilepton] and[ital lepton+jets] modes with[approx]100 pb[sup -1] of[ital p][ital[anti p]] Collider data at[radical]s= 1.8 TeV collected by the D[null] experiment at the Fermilab Tevatron. We have observed 37[ital t][ital[anti t]] candidate events while the estimated background is 13.4[+-] 3.0 events. The[ital t][ital[anti t]] production cross section has been measured to be 5.2[+-] 1.8 pb at a top quark mass of 170 GeV/c[sup 2].

The Fermilab Tevatron is currently the only collider capable of producing and studying top quarks. The dominant mechanism for top quark production at the Tevatron is t{bar t} production via the strong interaction. The precise measurement of the cross section of this process is a test of the QCD prediction. In Run II of the Tevatron it should be possible to achieve an experimental error on this cross section which is comparable or better than the current theoretical precision. This paper presents the basic event selection criteria for t{bar t} events at the Tevatron and the latest measurements of the t{bar t} cross section.
