The FeynRules project

Implementation and validation of new models
- B-L: implemetation completed, validation in MC tools ongoing (L. Basso).
- Dirac gauginos: Dirac gluinos are implemented. The implementation of the full model is ongoing (C. Duhr, P. Fox, B. Fuks, G. Kribbs, A. Martin).
- MSSM: Validation of the model in Sherpa has started and is ongoing (C. Duhr, B. Fuks, S. Schumann).
- NMSSM: Implementation of the model is complete. Validation again Whizard will soon start (Herwig++?) (C. Duhr, B. Fuks, J. Reuter).
- RPV MSSM: Implementation is achieved (C. Duhr, B. Fuks).

Validation procedure
- Any model can be put on the FeynRules website.
- Each model will be rated regarding the validation performed, from zero to four stars.
- Guidelines for validation
  - First star [DOC]
    - The model should be documented (description, references to the Lagrangian and field content, ...).
    - If the model is only a theory fragment, this should be stated.
    - Consistency of the input parameters (external vs. internal, all external plus a spectrum generator,...).
  - Second star [THEO]
    - Basic sanity checks: hermiticity of the Lagrangian, signs in the covariant derivatives, ...
    - If the Feynman rules are available in the literature, comparison (+ references).
    - If any theoretical work is available in the literature, reproduction (handmade or FeynArts/FormCalc or any other symbolic tool).
  - Second star [THEO]
