Abstract

We report a measurement of the t (t) over bar production cross section using the CDF II detector at the Fermilab Tevatron. The analysis is performed using 311 pb(-1) of p (p) over bar collisions at root 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(t (t) over bar) = (7.5 +/- 2.1(stat.) + (-2.2)(+3.3)(syst.) + (-0.4)(+0.5)(lumi.)) pb, which is consistent with the standard model prediction.
