Top pair production cross-section measurement in the all-hadronic channel at CDF and D0
Measurements of the t{bar t} production cross-section at {radical}s = 1.96 TeV in proton-antiproton collisions were performed by the CDF and D0 collaborations using t{bar t} final states where both W's decay hadronically. Each experiment uses luminosity of about 160 pb{sup -1} of data collected during Run II of the Fermilab Tevatron collider. Beside kinematical observables both experiments take advantage of identifying b jets based on lifetime tagging. While CDF counts the number of b-tags over background after a cut based analysis, D0 counts the excess of events after a neural network based kinematical selection and requiring a b-tagged jet. CDF obtains {sigma}{sub t{bar t}} = 7.8 {+-} 2.5(stat){sub -2.3}{sup +4.7}(syst); D0 {sigma}{sub t{bar t}} = 7.7{sub -3.3}{sup +3.4}(stat){sub -3.8}{sup +4.7}(syst) {+-} 0.5(lumi).
