+This model corresponds to the standard model amended with the following two operators (G is the gluon field strength tensor):

+
+with like-named associated coupling orders. The second operator involving the covariant derivative is typically not relevant as it is often rotated away in the basis using the equations of motion.
+The reference publication using this model is [ToAppear To appear], which also provides the validation material.
 
 == Model files
 
+We provide here the [/attachment/wiki/NLOModels/GGG_EFT_up_to_4point_loops.tar.gz UFO library] for this model is available and the original [/attachment/wiki/NLOModels/GGG.fr .fr model file].
+
+We stress that due to the complexity of the colour and Lorentz structures, not all counterterms have been computed and included in the model, but '''only those for one-loops connected to at most four gluons'''.
+
+Also, the length of the name of some fortran subroutines generated from this model will prevent their compilation, and this problem is only fixed in '''MG5_aMC v2.6.3+''', so check the version of your MG5_aMC distribution to ensure compatibility.
+
 == Validation
+
+The analytical expression for the squared one-loop interference amplitudes of order O(1/\Lambda^2), given in Eq. A.16 of the [ToAppear reference paper] can be numerically compared to [https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/MadLoopStandaloneLibrary MadLoop] output using this model.
+
+The cross-sections given in Table 6 of that paper can also be reproduced directly using MG5_aMC.
