## Description

This !MadGraph5 model is the implementation of the weak boson effective field theory described in arXiv:1205.4231 [hep-ph]. Namely, the model contains all the five dimension-six operators that modify the triple gauge boson vertices. Their coefficients can be set in the param_card.dat. The parameters in the param_card are the full coefficients, i.e. and are in TeV. The name are self-explanatory, is called CWWWL2 and similarly for and , the coefficients of the CP violating operators and are CPWWWL2 and CPWL2 respectively. The new interaction has also an order NP (for new physics) which is the power of () of the amplitude. For example, an amplitude with one vertex for a dimension-six operator is proportional to and has NP=2.
