Description of the model & references

Our NMSSM implementation in FeynRules is general in the sense that it is keeping all the flavour-violating and helicity-mixing terms in the Lagrangian and also all the possible additional CP-violating phases. In order to deal in a transparent way with the more than 100 parameters, our implementation follows the commonly used universal set of conventions provided by the Supersymmetry Les Houches Accord.

Sepcific instructions

  • The switch FeynmanGauge allows to choose between Feynman and unitarity gauge.
  • The flags $CKMDiag and $MNSDiag, being set to True or False, allow for CKM and PMNS matrices different from the identity or not.
  • A parameter file must be loaded before running the model, or all the parameters would have a value of -1 (ReadLHAFile[Input->"myfile"]).
