Description

We report on measurements of the top quark mass using dilepton and lepton+jet data collected with the D0 detector. These results are compared to the top mass extracted from the $t\bar{t}$ cross section using higher-order quantum chromodynamics calculations. We also present a direct measurement of the mass difference between top and antitop quarks ($\Delta m$) in lepton+jets $t\bar{t}$ final states using the “matrix element” method.
