Abstract
We present an analysis of dilepton events originating from t¯t production in p¯p collisions at √s = 1.8TeV at the Fermilab Tevatron Collider. The sample corresponds to an integrated luminosity of 109 ± 7pb-1. We observe nine candidate events, with an estimated background of 2.4 ± 0.5 events. We determine the mass of the top quark to be Mtop = 161 ± 17(stat) ± 10(syst)GeV/c2. In addition, we measure a t¯t production cross section of 8.2+4.4 -3.4pb (where Mtop = 175GeV/c2 has been assumed for the acceptance estimate). © 1998 The American Physical Society.
