The data were collected by the DØ experiment during the 1992–1996 run of the Fermilab Tevatron Collider. A total of 80 candidate events is observed with an expected background of 38.8±3.3 events. For a top quark mass of 172.1GeV/c(2), the measured cross section is 5.69±1.21(stat)±1.04(syst)pb.Article10.1103/PhysRevD.67.012004openAccess
