We present a measurement of t¯t production in p¯p collisions at √s = 1.8TeV from 110pb-1 of data collected in the all-jets decay channel with the D0 detector at Fermilab. A neural network analysis yields a cross section of 7.1 ± 2.8(stat) ± 1.5(syst)pb at a top quark mass (mt) of 172.1GeV/c2. Using previous D0 measurements from dilepton and single lepton channels, the combined D0 result for the t¯t production cross section is 5.9 ± 1.2(stat) ± 1.1(syst)pb for mt = 172.1GeV/c2.
