Matching NLO QCD Corrections in WHIZARD with the POWHEG scheme

Abstract

Building on the new automatic subtraction of NLO amplitudes in WHIZARD, we present our implementation of the POWHEG scheme to match radiative corrections consistently with the parton shower. We apply this general framework to two linear collider processes, $e^{+}{e}^{-}\to t\bar{t}$ and $e^{+}{e}^{-}\to t\bar{t}H$.
