Abstract
We present a measurement of the top quark pair (tt‾) production cross section in pp‾ collisions at √s = 1.96 TeV using events with two charged leptons in the final state. This analysis utilizes an integrated luminosity of 224-243 pb-1 collected with the DØ detector at the Fermilab Tevatron Collider. We observe 13 events in the e+e-, eμ and μ+μ- channels with an expected background of 3.2±0.7 events. For a top quark mass of 175 GeV, we measure a tt‾ production cross section of σtt‾ = 8.6+3.2-2.7(stat)±1.1(syst)±0.6(lumi) pb, consistent with the standard model prediction.
