Description

We present the computation of the differential cross section for the process pp -> W+ W- b bbar -> e mu b bbar + X at NLO~QCD accuracy matched to Shower Monte Carlo. We include all resonant and non-resonant contributions. This is achieved by fully taking into account the effect of off-shell t-quarks and off-shell W-bosons in the complex mass scheme. We also present a program called DECAYER that can be used to let the t-quarks present in the event files for pp -> t tbar +X processes decay including both the finite width of the t-quarks and spin correlations.
