Top Physics in WHIZARD

Understand

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.
