Description of the model
This model describes the effective coupling of the Higgs boson to gluons and photons. The effective theory is obtained by integrating out the topquark loop through which the higgs couples to gluons and photons. The corresponding effective theory for a pseudoscalar is also included.
The values of the effective couplings correspond to those given in the heft model of the MadGraph/MadEvent distribution.

Model files
 HiggsEffective.fr This is the main file.
 This model needs the model file of the SM implementation of FeynRules.
Instructions
The model is loaded by merging the model files SM.fr and HiggsEffective.fr (the two files must be stored in the same directory, see the [:UserManual:user manual]).
The implementation allows for the use of the Feynman gauge in the SM. Feynman gauge is not supported for this model.
Examples
 HiggsEffective.nb : This is an example Mathematica® notebook that loads the model and calculates Feynman rules.
 HiggsEffective.tex : This is TeX output written by FeynRules.
