Abstract
We present a measurement of the tt-bar cross section using high-multiplicity jet events produced in pp-bar collisions at s√=1.96 TeV. These data were recorded at the Fermilab Tevatron Collider with the D0 detector. Events with at least six jets, two of them identified as b jets, were selected from a 1 fb(−1) data set. The measured cross section, assuming a top quark mass of 175 GeV/c2, is 6.9±2.0 pb, in agreement with theoretical expectations.
