    Abstract

    The D0 Collaboration has performed a measurement of the top quark mass mt based on six candidate events for the process tt- → bW+bW-, where the W bosons decay to eν or μν. This sample was collected during an exposure of the D0 detector to an integrated luminosity of 125pb-1 of √ s = 1.8 TeV pp collisions. We obtain mt = 168.4 ± 12.3(stat) ± 3.6(syst) GeV/c2, consistent with the measurement obtained using single-lepton events. Combination of the single-lepton and dilepton results yields mt = 172.0 ± 7.5 GeV/c2.
