== Model files ==
During the lectures, you will be able to implement from scratch a model for a supersymmetric (SUSY) QCD theory. The implementation will be performed in three steps which will illustrate the different features of !FeynRules.

 * The good old way, using four-component fermions and scalar fields (not the best way for SUSY theories).
 * A better approach, using two component fermions instead of four-component ones
 * The best method for SUSY: using superfields.

Before adding the superfields to the model files, you will have to add the charge-conjugate scalar and fermion for the right-handed (s)quark. Since this will not be done during the lectures, please download the add-on to merge to your model file: [/attachment/wiki/SchoolKias/FeynRules/addon.fr addon.fr]
