Abstract

The D0 Collaboration has performed a measurement of the top quark mass m_t based on six candidate events for the process tt\ensuremath→bW⁺bW^\ensuremath-, where the W bosons decay to e\ensuremathν or \ensuremathμ\ensuremathν. This sample was collected during an exposure of the D0 detector to an integrated luminosity of 125pb^\ensuremath-1 of √(s)\phantom\rule0ex0ex=\phantom\rule0ex0ex1.8\phantom\rule0ex0exTeVpp collisions. We obtain m_t\phantom\rule0ex0ex=\phantom\rule0ex0ex168.4\ifmmode±\else\textpm\fi12.3(stat)\ifmmode±\else\textpm\fi3.6(syst)\phantom\rule0ex0exGeV/c², consistent with the measurement obtained using single-lepton events. Combination of the single-lepton and dilepton results yields m_t\phantom\rule0ex0ex=\phantom\rule0ex0ex172.0\ifmmode±\else\textpm\fi7.5GeV/c².
