Abstract

A measurement of the top quark pair production cross section in proton antiproton collisions at an interaction energy of sqrt(s)=1.96 TeV is presented. This analysis uses 405±25 pb-1 of data collected with the D0 detector at the Fermilab Tevatron Collider. Fully hadronic t[overline t] decays with final states of six or more jets are separated from the multijet background using secondary vertex tagging and a neural network. The t[overline t] cross section is measured as sigmat[overline t]=4.5-1.9+2.0(stat)-1.1+1.4(syst)±0.3(lumi) pb for a top quark mass of mt=175 GeV/c2.
