Abstract
We present three measurements of the top-quark mass in the lepton plus jets channel with approximately 1.9 fb[superscript -1] of integrated luminosity collected with the CDF II detector using quantities with minimal dependence on the jet energy scale. One measurement exploits the transverse decay length of b-tagged jets to determine a top-quark mass of 166.9[subscript -8.5][superscript +9.5](stat)±2.9(syst) GeV/c[superscript 2], and another the transverse momentum of electrons and muons from W-boson decays to determine a top-quark mass of 173.5[subscript --8.9][superscript +8.8](stat)±3.8(syst) GeV/c[superscript 2]. These quantities are combined in a third, simultaneous mass measurement to determine a top-quark mass of 170.7±6.3(stat)±2.6(syst) GeV/c[superscript 2].
