    3030'''Note''': the top partner width is set to 1 GeV by default, but the actual values must be evaluated and adjusted explicitly in MadGraph (specifying all the corresponding decay channels), for a fixed choice of the above parameters.

    32 These parameters are combined internally in the FeynRules model file 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) when loading the FeynRules model, 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.
