            |   | 11 | This model is an extension of the SM, including a scalar diquark with quantum numbers |

            |   | 28 |    * This model needs the model file of the [wiki:StandardModel SM implementation] of !FeynRules.  | 
          
          
            |   | 29 |    * [source:trunk/models/TripletDiquarks/TripletDiquarks.nb TripletDiquarks.nb]: This is an example Mathematica notebook that loads the model and calculates Feynman rules.   |

            |   | 31 | The implementation assumes generic Yukawa matrices for the couplings between the quarks and the scalar diquarks.  | 
          
          
            |   | 32 | The mixing matrices can however be constrained to be diagonal by using the following [source:trunk/models/TripletDiquarks/MFV.rst restriction file]. |
