The measurements are performed in the lepton + jets decay channels (e + jets and mu + jets) and the dilepton decay channels (e(+)e(-), mu(+)mu(-), and mu(+/-)e(-/+)). The t (t) over bar differential cross section is measured as a function of kinematic properties of the final-state charged leptons and jets associated to b quarks, as well as those of the top quarks and the t (t) over bar system. The data are compared with several predictions from perturbative QCD calculations up to approximate next-to-next-to-leading-order precision. No significant deviations from the standard model are observed.
