First steps towards WHIZARD + NLO — Bijan Chokoufe1, Wolfgang Kilian2, Jürgen Reuter1, and •Christian Weiss1 — 1DESY Hamburg — 2Uni Siegen
WHIZARD is a multi-purpose event generator for hadron- and lepton-colliders, considering the standard model as well as a multitude of BSM models. The current version of the program is only capable of automatically performing leading-order calculations, contributions of higher virtual orders being available for some specific kinds of processes. However, many applications require at least next-to-leading order accuracy. We present a first extension of WHIZARD which can also deal with processes at next-to-leading order, using the Frixione-Kunszt-Signer subtraction scheme. The program structure is briefly explained, focussing on the various components of the calculation and the corresponding interface to one-loop programs like GoSam. Finally, first results for NLO massless QCD are presented.
