The WHIZARD / O'Mega interface (C. Speckner) --- UNDER CONSTRUCTION


The WHIZARD / O'Mega interface generates the model files necessary for the inclusion of a FeynRules model into the WHIZARD / O'Mega framework. All versions of WHIZARD / O'Mega >= 1.92 are supported.

Usage: all versions

As all other interfaces, the WO interface is invoked by calling WriteWOOuput. Three syntax variants are admissible:

  1. WriteWOOutput[Lagrangian, Options]
  1. WriteWOOutput[{LagrangianList}, Options]
  1. WriteWOOutput[Null, WOVertexList->{VertexList], Options]

Version 1. operates on a single Lagrangian, while 2. operates on a list of Lagrangians and 3. takes a list of FeynmanRules? as an argument. The following options are available:

  • WOVertexList: If =!= Null, this is interpreted as a list of Feynman rules and overrides any Lagrangian (or -List) specified (in this case, Null is accepted as first argument).
  • WOModelName: The name with which the model will be identified in WO. Note that all models for W1.9x have to start with "fr" (e.g. WOModelName->"fr_sm") if they are to be picked up by WO1.9x without user intervention (no such restriction exists for W2). Beware that the interface my modify this name if it doesn't fit into the WO naming schemes --- double check the generated messages to be sure.
  • WOMaxNcf: Upper limit on the number of generated color flows which the generated code will be able to handle (essentially n_8 - n_3 / 2, where n_8 is the maximum number of external triplets and n_3 that of external singlets). Irrelevant for W2; also, the technically experienced user can change this after generation in
