Abstract

We present an analysis of dilepton events originating from tt¯ production in pp¯ collisions at s=1.8TeV at the Fermilab Tevatron Collider. The sample corresponds to an integrated luminosity of 109±7pb1. 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 tt¯ production cross section of 8.23.4+4.4pb (where Mtop=175GeV/c2 has been assumed for the acceptance estimate).
