Measurement Of The P Anti P T Anti T Production Cross Section And The Top Quark Mass At Su

We report the measurements of the t{bar t} production cross section and of the top quark mass using 1.02 fb−1 of p{bar 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 [sigma]{sub t{bar t}} = 8.3 ± 1.0(stat.){sup +2.0}{sub -1.5}(syst.) ± 0.5(lumi.) pb, which is consistent with the standard model prediction. The top quark mass of 174.0 ± 2.2(stat.)±4.8(syst.) GeV/c2 is derived from a likelihood fit incorporating reconstructed mass distributions representative of signal and background.
