Abstract

The measurement of the top-quark mass in lepton+jets channels provides the most precise determination of the top-quark mass from Tevatron Run I data.In the Run II phase, the CDF and DØ experiments have already collected more than 1 fb -1 of data in the period 2002-2005.The preliminary analyses presented here use a subset of up to 320 pb -1 .With these statistics and an in-situ calibration of the jet energies, a single analysis now surpasses the precision of the previous world average.
