Python interface

  • Description: development of a FeynRules Python interface, which will be used by MG, Herwig and Golem.
  • Names: Claude, David, Olivier, Will, Thomas Reiter
  • Status:
    • We decided that a model is a Python package, where particles, parameters, etc. are represented as objects. The package will be self-contained in the sense that it provides everything required for the module (definition of the classes, etc.)
    • All files are written by FeynRules. The only missing piece is the definition the anti particles as objects in Python.
  • To-do:
    • Some tuning for the parameters needs to be done, especially "Waterfall structure".
    • Some python files need to be added to the package, e.g. , functions like sqrt, sin, etc.
    • We have now the option to matrices as matrices, rather than component by component. This needs to be discussed and developped further. -> Right now we all seem to go for the component by component option.
    • The parts dealing with the vertices, couplings, etc. need to be written. Will is working on splitting the FR vertices into triplets according to color, lorentz_structure and coupling. After this is done, Claude will create the writing routines for vertices. - done -
    • David is developing the Herwig part of the Python interface.
