 v1 == 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. 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_W~WW and O_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.

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.
