Description of the model
This model is an extension of the SM, where a new fourth generation of fermions, a t' and a b' with SM couplings, is added. The CKM matrix is a generic 3x3 matrix. The particle content and the vertices of the model are summarized in the following pdf file.
Model files
- 4Gen.fr: This is the main file.
- 4Gen.nb: This is an example Mathematica notebook that loads the model and calculates Feynman rules.
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. All fermion masses are put to zero, except for the top, the bottom and the Tau lepton masses. Furthermore, in the CalcHep files, the CKM matrix is real.
