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.
- The platform (Linux version, ...), the Mathematica version, the FeynRules version and the MC generator versions, if relevant, used for the checks must be indicated.
- 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).
- Third star [1MC]
- Check some basic processes like Drell-Yan or bhabha scattering and that the MC is producing reliable results (running of alpha_s, QED running, ...).
- Gauge invariance (e.g. several gauges in CalcHep, numerical checks in other MC tools).
- Reproduce SM results for sectors independent on new physics.
- Behaviour at high energy (unitarity cancellations).
- Produce numerical tables for cross sections or any observables for future references.
- Fourth star [nMC]
- Show that the [1MC] step can be reproduced by more than one MC generators.
- Produce some comparison tables for future references.
- First star [DOC]
- Copyright issues
- How to give credits to all people involved in the chain Model Building > FeynRules inmplementation > Monte Carlo simulations?
- Every FeynRules implementation should cite the reference papers of the model.
- All this information should be encoded in the FeynRules model files via M$Information.
- Can all this information be passed on through the whole chain down to the MC generators?
- Every FeynRules implementation should cite the reference papers of the model.
