Abstract: In this talk we summarize the top physics setup in the event generator WHIZARD with a main focus on lepton colliders. This includes full six-, eight- and ten-fermion processes, factorized processes and spin correlations. For lepton colliders, QCD NLO processes for top quark physics are available and will be discussed. A special focus is on the top-quark pair threshold, where a special implementation combines a non-relativistic effective field theory calculation augmented by a next-to-leading threshold logarithm resummation with a continuum relativistic fixed-order QCD NLO simulation.

Keyword(s): effective field theory: nonrelativistic ; spin: correlation ; higher-order: 1 ; quantum chromodynamics ; numerical calculations ; lepton ; Monte Carlo ; resummation
