We measure the production cross section of t{bar t} events in p{bar p} collisions at √s = 1.96 TeV. The data was collected by the CDF experiment in Run 2 of the Tevatron accelerator at the Fermi National Accelerator Laboratory between 2002 and 2007. 1.7 fb−1 of data was recorded during this time period. We reconstruct t{bar t} events in the lepton+jets channel, whereby one W boson - resulting from the decay of the top quark pairs - decays leptonically and the other hadronically. The dominant background to this process is the production of W bosons in association with multiple jets. To distinguish t{bar t} from background, we identify soft electrons from the semileptonic decay of heavy flavor jets produced in t{bar t} events. We measure a cross section of [sigma]{sub p{bar p}} = 7.8 ± 2.4(stat) ± 1.6(syst) ± 0.5(lumi).

We measure the production cross section of t$ar{t}$ events in p$ar{p}$ collisions at √s = 1.96 TeV. The data was collected by the CDF experiment in Run 2 of the Tevatron accelerator at the Fermi National Accelerator Laboratory between 2002 and 2007. 1.7 fb-1 of data was recorded during this time period. We reconstruct t$ar{t}$ events in the lepton+jets channel, whereby one W boson - resulting from the decay of the top quark pairs - decays leptonically and the other hadronically. The dominant background to this process is the production of W bosons in association with multiple jets. To distinguish t$ar{t}$ from background, we identify soft electrons from the semileptonic decay of heavy flavor jets produced in t$ar{t}$ events. We measure a cross section of ?$ar{p}$ = 7.8 ± 2.4(stat) ± 1.6(syst) ± 0.5(lumi).
