    Abstract
    We have studied tt-bar production using multijet final states in pp-bar collisions at a center-of-mass energy of 1.8 TeV, with an integrated luminosity of 110.3 pb(-1). Each of the top quarks with these final states decays exclusively to a bottom quark and a W boson, with the W bosons decaying into quark-antiquark pairs. The analysis has been optimized using neural networks to achieve the smallest expected fractional uncertainty on the tt-bar production cross section, and yields a cross section of 7.1±2.8 (stat)±1.5 (syst) pb, assuming a top quark mass of 172.1 GeV/c(2). Combining this result with previous DØ measurements, where one or both of the W bosons decay leptonically, gives a tt-bar production cross section of 5.9±1.2 (stat)±1.1 (syst)pb.
