== Description ==

This !MadGraph5 model is the implementation of the top effective field theory described in arXiv:1008.3869 [hep-ph]. Namely, the model contains all the dimension six operators that are interfering with the leading tree-level SM amplitude for the top decay and both single top and top pair productions. This model is particularly suited to study the largest effects of non-resonant new physics (e.g. composite top and Higgs) in a model independent way. All the four-fermion operators are flavor diagonal and universal for the two lightest generations.
