Measurement of the tt̄ production cross section in pp̄ collisions at s=1.96TeV in the all hadronic decay mode
2006
The authors report a measurement of the t{bar t} production cross section using the CDF II detector at the Fermilab Tevatron. The analysis is performed using 311 pb{sup -1} of p{bar p} collisions at {radical}s = 1.96 TeV. The data consist of events selected with six or more hadronic jets with additional kinematic requirements. At least one of these jets must be identified as a b-quark jet by the reconstruction of a secondary vertex. The cross section is measured to be {sigma}{sub t{bar t}} = 7.5 {+-} 2.1(stat.){sub -2.2}{sup +3.3}(syst.){sub -0.4}{sup +0.5}(lumi.) pb, which is consistent with the standard model prediction.
