摘要

We present the NLO QCD corrections to the processes pp and p(p) over bar -> W(+)W(-)b(b) over bar including leptonic decays of the W bosons. Non-resonant contributions as well as diagrams with doubly resonant and singly resonant top quark propagators are fully taken into account. We employ the narrow width approximation to perform the decays of the W bosons; spin correlations are however preserved. We also calculate observables relevant for top quark mass measurements, and study the impact of kinematical requirements and different scale choices on t(t) over bar asymmetries.
