摘要：

We present a measurement of the <t(t)over bar> production cross section in <p(p)over bar> collisions at root s = 1.8 TeV by the DO experiment at the Fermilab Tevatron. The measurement is based on data from an integrated luminosity of approximately 125 pb(-1) accumulated during the 1992-1996 collider run. We observe 39 <t(t)over bar> candidate events in the dilepton and lepton + jets decay channels with an expected background of 13.7 +/- 2.2 events. For a top quark mass of 173.3 GeV/c(2), we measure the <t(t)over bar> production cross section to be 5.5 +/- 1.8 pb.
