Abstract

We measure the top quark mass m_t using tt pairs produced in the D0 detector by √(s)\phantom\rule0ex0ex=\phantom\rule0ex0ex1.8TeVpp collisions in a 125pb^\ensuremath-1 exposure at the Fermilab Tevatron. We make a two constraint fit to m_t in tt\ensuremath→bW⁺bW^\ensuremath- final states with one W decaying to qq and the other to e\ensuremathν or \ensuremathμ\ensuremathν. Events are binned in fit mass versus a measure of probability for events to be signal rather than background. Likelihood fits to the data yield m_t\phantom\rule0ex0ex=\phantom\rule0ex0ex173.3\ifmmode±\else\textpm\fi5.6(stat)\ifmmode±\else\textpm\fi6.2(syst)GeV/c².
