Title: Measurement of the t anti-t production cross section in p anti-p collistions at s**(1/2) = 1.96-TeV in dilepton final states

Abstract

The authors present a measurement of the top quark pair (t{bar t}) production cross section in p{bar p} collisions at {radical}s = 1.96 TeV using events with two charged leptons in the final state. This analysis utilizes an integrated luminosity of 224-243 pb{sup -1} collected with the D0 detector at the Fermilab Tevatron Collider. They observe 13 events in the e{sup +}e{sup -}, e{mu} and {mu}{sup +} {mu}{sup -} channels with an expected background of 3.2 {+-} 0.7 events. For a top quark mass of 175 GeV, we measure a t{bar t} production cross section of {sigma}{sub t{bar t}} = 8.6{sub -2.7}{sup +3.2}(stat) {+-} 1.1(syst) {+-} 0.6(lumi) pb, consistent with the standard model prediction.
