    119 '''This file has to be loaded together with the MWT.fr.'''
     119!HiggsEffective.fr has to be loaded together with the FeynRules file for the MWT model, i.e. using the command {{{LoadModel[HiggsEffective.fr, MWT.fr]}}} where MWT.fr indicates the name of the MWT model file.
     120The value of the effective coupling coincides with the full one loop result, and depends on the values assumed by the other parameters of the model. For practical reasons though the effective coupling is introduced as an external parameter. Anyway its value doesn't need to be introduced at the Lagrangian level (i.e. in the FeynRules file) but will be calculated by the modified calculator for MadGraph, that computes its value based on the full one loop result. Therefore this extension can be used currently only with MadGraph. Note that the effective coupling is independent of the new dynamics because the Higgs-fermions couplings are not modified in the MWT implementation respect to the SM.
