    3232These parameters are combined internally in FeynRules to match the model-independent prescription presented above. For consistency, all light quarks included in the proton definition are restricted to be massless (5F scheme), except for the top, bottom and tau lepton masses. The default model loads the real 3X3 CKM matrix given in [attachment:Parameters.pdf] as an external parameter. In general, the presence of new top partners induce model-dependent corrections to the mixings between the novel heavy fermions and the lighter quark families, which are not taken into account here.
     
    3535Below we provide the tarballs containing the main model files and outputs. The UFO model files have been compiled with Feynrules 1.4.9, and are compatible with MadGraph 1.5.11. The CH model files require the latest updated version of CalcHep, and have been obtained using version 1.7.178 of FeynRules. To import the model into MadGraph, it is enough to unzip the UFO directory into the models subdirectory of MadGraph, and load the model using the "import model TsingletVL_UFO" command.
