Abstract

We describe the multi-purpose Monte-Carlo event generator WHIZARD for the simulation of high-energy particle physics experiments. Besides the presentation of the general features of the program like SM physics, BSM physics, and QCD effects, special emphasis will be given to the support of the most accurate simulation of the collider environments at hadron colliders and especially at future linear lepton colliders. On the more technical side, the very recent code refactoring towards a completely object-oriented software package to improve maintainability, flexibility and code development will be discussed. Finally, we present ongoing work and future plans regarding higher-order corrections, more general model support including the setup to search for new physics in vector boson scattering at the LHC, as well as several lines of performance improvements.

Highlights

WHIZARD [1] is a general event generator for all kinds of scattering and decay processes at highenergy hadron and lepton colliders.The default matrix element generator of WHIZARD is O’Mega [2]
We report the recent progress in the technical development of the program as well as new physics features
Two main points to be mentioned are the special focus on lepton-collider beam spectra, which involves a detailed account of correlated beam spectra, arbitrary polarization and interfaces to the machine simulation

Summary

Introduction

WHIZARD [1] is a general event generator for all kinds of scattering and decay processes at highenergy hadron and lepton colliders.The default matrix element generator of WHIZARD is O’Mega [2]. 2. Program Overview WHIZARD – initiated along the lines of the TESLA design study [5] to provide improved simulations for electroweak processes at lepton colliders – has developed into a universal generator for partonic events at all types of present and future (lepton and hadron) colliders.
