   Abstract:
   We report the measurements of the t[overline t] production cross section and of the top quark mass using 1.02 fb-1 of p[overline p] data collected with the CDF II detector at the Fermilab Tevatron. We select events with six or more jets on which a number of kinematical requirements are imposed by means of a neural network algorithm. At least one of these jets must be identified as initiated by a b-quark candidate by the reconstruction of a secondary vertex. The cross section is measured to be sigmat[overline t]=8.3$\pm$1.0(stat)-1.5+2.0(syst)$\pm$0.5(lumi) pb, which is consistent with the standard model prediction. The top quark mass of 174.0$\pm$2.2(stat)$\pm$4.8(syst) GeV/c2 is derived from a likelihood fit incorporating reconstructed mass distributions representative of signal and background.
