Abstract
We present a measurement of the mass of the top quark from proton-antiproton collisions recorded at the CDF experiment in Run II of the Fermilab Tevatron. We analyze events from the single lepton plus jets final state (). The top-quark mass is extracted using a direct calculation of the probability density that each event corresponds to the 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 boson mass. Using 167 events observed in of integrated luminosity, we achieve the single most precise measurement of the top-quark mass, .
