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

The events can be written to file in HepMC, LHEF, LCIO or ASCII format.

Tree-level matrix elements are generated automatically for arbitrary
partonic processes by calling the O'Mega matrix element generator.
Matrix elements obtained by alternative methods (e.g., including loop
34
corrections) are interfaced as well via the BLHA interface, from

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 or eight final-state
particles.  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.  Currently, WHIZARD supports the
Standard Model, optionally with anomalous couplings (for gauge bosons, 
the Higgs boson, and the top quark), the MSSM, the NMSSM, several types 
of Little Higgs models, Universal Extra Dimensions, the 3-site Higgsless
moose model, and a generic Z' model. Model extensions or completely 
different models can be added. Almost arbitrary models might be added via
