     8=== Description of the model ===

     10This 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 parametrized by Vtps and Vtpb, which are supposed small, and to leading order in the expansion in Vtps and Vtpb it is given by,

     24== Matrix element generator files ==
     25Below 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.
