 v2 == Description == This FeynRules 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. c,,i,,/Lambda^2^ and are in TeV^-2^. The name are self-explanatory, c,,WWW,,/Lambda^2^ is called CWWWL2 and similarly for c,,W,, and c,,B,, , the coefficients of the CP violating operators $O_{\tilde{W}WW}$ and $O_{\tilde{W}}$ are CPWWWL2 and CPWL2 respectively. The new interaction has also an order NP (for new physics) which is the power of ($1/\Lambda$) of the amplitude. For example, an amplitude with one vertex for a dimension-six operator is proportional to $1/\Lambda^2$ and has NP=2.
