We analyze events from the single lepton plus jets final state (t(t)over bar -> W(+)bW(-)(b)over bar -> lvbq(q)over bar(')(b)over bar). The top-quark mass is extracted using a direct calculation of the probability density that each event corresponds to the t(t)over bar final state. The probability is a function of both the mass of the top quark and the energy scale of the calorimeter jets, which is constrained in situ by the hadronic W boson mass. Using 167 events observed in 955 pb(-1) of integrated luminosity, we achieve the single most precise measurement of the top-quark mass, 170.8 ± 2.2(stat.) ± 1.4(syst.) GeV/c^2.This work was supported by the US Department of Energy and National Science Foundation; the Italian Istituto Nazionale di Fisica Nucleare; the Ministry of Education, Culture, Sports, Science, and Technology of Japan; the Natural Sciences and Engineering Research Council of Canada; the National Science Council of the Republic of China; the Swiss National Science Foundation; the A.P.
