Description of the model
This model is an extension of the SM, including a scalar diquark with quantum numbers
SU(3)  SU(2)  U(1)Y  3  1  1/3 
For the sextet diquark implementation, see sextet diquark model. The particle content and the vertices of the model are summarized in the following pdf file.
The implementation of the model is based on
" QCD Corrections to Scalar Diquark production at Hadron Colliders ", T. Han, I. Lewis, T. McElmurry, JHEP 1001:123,2010, arXiv:0909.2666.
Model files
 TripletDiquarks.fr: This is the main file.
 This model needs the model file of the SM implementation of FeynRules.
 TripletDiquarks.nb: This is an example Mathematica notebook that loads the model and calculates Feynman rules.
The implementation assumes generic Yukawa matrices for the couplings between the quarks and the scalar diquarks. The mixing matrices can however be constrained to be diagonal by using the following restriction file.
Matrix element generator files
Below we give tarballs containing the model files generated by FeynRules for the various matrix element generaotrs for which a FeynRules interface exists. Not that in these files all fermion masses are put to zero, except for the top, the bottom and the Tau lepton masses.
Triplet_Diquarks_CH.tar.gz  The model files for CalcHep. 
Triplet_Diquarks_FA.tar.gz  The model files for FeynArts. 
Triplet_Diquarks_MG.tar.gz  The model files for MadGraph 4. 
Triplet_Diquarks_SH.tar.gz  The model files for Sherpa.
