= Welcome to the WHIZARD Wiki =

The long awaited release of version 2 of WHIZARD was unleashed on Monday, April 12th, 2010 ...

== Installation ==

Details about the WHIZARD 2 installation can be found [wiki:installation here.]

== Getting Started ==

=== Examples ===

Here's a list of simple, but complete physics applications that can get you started immediately.  Just run
{{{
   whizard -r example.sin
}}}
after compiling and installing WHIZARD.

 * [wiki:ExampleCascadeDecays Angular correlations in SUSY cascade decays at LHC]
 * [wiki:ExampleWendpoint W endpoint at the LHC]
 * [wiki:ExampleZprime Z' search at LHC]
 * [wiki:ExampleZlineshape Z lineshape at LEP1]
 * [wiki:ExampleCC10 W pairs at LEP2]
 * [wiki:ExampleLEPHiggs Higgs search at LEP2]
 * [wiki:ExampleEEWW W pairs with polarized beams at ILC]
 * [wiki:ExampleLEPJets MLM jet matching at LEP]

Caveat: most of these examples are distributed with very minor variations in the directory share/examples and installed in .../share/whizard/examples/.

=== (Uncommon) Build Problems ===

[wiki:BuildProblems Here]'s a [wiki:BuildProblems list of not so common problems] that you might encounter when building WHIZARD that didn't make it into the 2.0.0 release [source:tags/release_2.0.0/INSTALL INSTALL file]. See here the most recent [source:trunk/INSTALL INSTALL file].   

The following problem applies only to version 2.0.0 and is solved in all follow-up
versions! When you compile with the NAG 5.2 Fortran 2003 Compiler and encounter the following problem: 
{{{
Panic: ../../../../src/omega/tests/omega_interface.f90: Unexpected cdtype (0) in upsinfo_cdtype
Internal Error -- please report this bug
Abort
}}}
then you probably compiled with a -g flag. Please note the following [http://projects.hepforge.org/whizard/compilers.html#NAG-note remark on NAG compilers].


== The !FeynRules interface ==

Release note:

The official 1.6.x versions of !FeynRules do contain a version of this interface. So only in the case of the old 1.4.x release series which does not support WHIZARD out of the box you have to download and install the interface separately. In the first case, just download the latest !FeynRules version
from [http://feynrules.phys.ucl.ac.be]. In the latter case, please download the most current version from our [http://www.hepforge.org/downloads/whizard download page] and untar the archive (note that the tarballs don't carry version number, but are instead enumerated by the creation date as in FR-WO_Interface.yyyy.mm.dd.tar.gz). Use the provided {{{install.sh}}} script to install the interface into the !FeynRules distribution:

{{{./install.sh /path/to/feynrules}}}

Prior to installation, the installer performs a version check. If the interface has not been tested with the !FeynRules version, it will refuse to continue the installation. Although we try to keep the Interface in sync with the latest public version, it may happen that you encounter a version not yet validated. In this case, please drop us a note and try the "-f" option which overrides the version check.

For further information on using the interface, please consult the [http://feynrules.phys.ucl.ac.be/twiki/pub/Main/WebHome/Manual_a4.pdf FeynRules manual] and the WHIZARD / O'Mega page on the [https://server06.fynu.ucl.ac.be/projects/feynrules/wiki/WhizardInterface FeynRules Wiki].
