    4040* The present '''NMSSM model''' has been validated against the first NMSSM implementation in !FeynRules, using component fields. We calculate the Feynman rules associated to the difference of the old and the new Lagrangian, and obtains an empty set of rules.
    41 * The '''old NMSSM implementation''' has been validated as follow. We have compared of the built-in !Whizard model files with the !FeynRules generated ones (!CalcHep and !MadGraph) through the calculation of various 2 to 2 cross sections. For each implementation, we have fixed all the parameters to those of  [/attachment/wiki/NMSSM/valid.dat a specific benchmark point] and set the __widths of the particles to zero__. We have calculated 2 to 2 cross sections related to the production of any pair of particles from a Standard Model initial state of __2x600 GeV__, in unitarity gauge. The results are available here [/attachment/wiki/NMSSM/validation.tgz validation.tgz].
