The manual is available in HTML and in PostScript and PDF formats. Note that the manual needs (and will get) a major update.

The current version is 1.92 (last update: Apr 29 2008).

The WHIZARD project is a part of the Strategic Helmholtz Alliance Physics at the Terascale.

WHIZARD is a program system designed for the efficient calculation of multi-particle scattering cross sections and simulated event samples.

Tree-level matrix elements are generated automatically for arbitrary partonic processes by using the Optimized Matrix Element Generator O'Mega. Matrix elements obtained by alternative methods (e.g., including loop corrections) may be interfaced as well. The program is able to calculate numerically stable signal and background cross sections and generate unweighted event samples with reasonable efficiency for processes with up to six final-state particles; more particles are possible.

Polarization is treated exactly for both the initial and final states. Final-state quark or lepton flavors can be summed over automatically where needed. For Linear Collider physics, beamstrahlung (CIRCE) and ISR spectra are included for electrons and photons. For hadron collider physics, an interface to the standard PDFLIB is provided. The events can be fragmented internally using the built-in PYTHIA interface or written to file in standard formats, including ASCII, STDHEP, or the Les Houches event format.

Currently, WHIZARD supports the Standard Model (optionally, with anomalous couplings), the MSSM, Little Higgs models, Zprime models, and supports gravitinos and gravitons. Model extensions or completely different models can be added.
