Top Quark Mass Measurements
Abstract
Preliminary results on the measurement of the top quark mass (mt) at the Tevatron Collider are presented. In the dilepton decay channel, the CDF Collaboration measures mt=175.0(+17.4)(-16.9)(stat.)+/-8.4(syst.) GeV/c2, using a sample of ~126 pb-1 of proton-antiproton collision data at sqrt(s)=1.96 TeV (Run II). In the lepton plus jets channel, the CDF Collaboration measures 177.5(+12.7)(-9.4)(stat.)+/-7.1(syst.) GeV/c2, using a sample of ~102 pb-1 at sqrt(s)=1.96 TeV. The D0 Collaboration has newly applied a likelihood technique to improve the analysis of ~125 pb-1 of proton-antiproton collisions at sqrt(s)=1.8 TeV (Run I), with the result: mt=180.1+/-3.6(stat.)+/-3.9(syst.) GeV/c2. The latter is combined with all the measurements based on the data collected in Run I to yield the most recent and comprehensive experimental determination of the top quark mass: mt=178.0+/-2.7(stat.)+/-3.3(syst.) GeV/c2
