Working Group 2 - Interface development

• I. Herwig interface.
  • Description: development of a FeynRules-Herwig interface.
  • Names: David, Claude.
  • Status: .
  • To-do: .

• II. Helas.
  • Description: automatized generation of Helas routines from FeynRules.
  • Names: Olivier, Claude, Will, Priscila, David
  • Status:
    • We have a defined format for the FR input
    • We have produce our first generated automaticaly Helas Routine from FeynRules.
    • Testing those routines is in progress
  • To-do:
    • Python Optimization (code quite slow at the time)
    • Regenerate all the Helas routine and test those against the old one
    • Implement the Scalar in the FortranWriter
    • Implement Helas Optimization
    • Implement a mode for complex couplings/masses

• III. FeynArts interface.
  • Description: inclusion of the higher dimensional operators in FeynArts.
  • Names: Celine, Thomas
  • Status:
    • Format of the FR output for the dirac indices is defined (Implementation in FR in progress).
    • addition of the dirac indices in FeynArts/FormCalc in progress.
    • Test in progress : EQCD done (FA only), composite top (FR files used in FA), BFSM (comparison with stock version started).
  • To-do:
    • Define format for the levi-civita tensor and implement it.
    • generate declaration file for FormCalc.
    • Merging of the vertices in FR.
    • Test SILH + renormalizable theories.
