    1414This !MadGraph5 model is the implementation of the dimension-eight operators inducing neutral triple gauge boson couplings (nTGC). Namely, the model contains all the four dimension-eight operators that modify the neutral 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. $C_i/\Lambda^4$ and are in TeV$^-2$. The name are self-explanatory, $C_{\widetilde{B}W}/\Lambda^4$ is called CBtWL4, $C_{BW}/\Lambda^4$ is called CBWL4 and similarly for $C_WW$ and $C_BB$. The new interaction has also an order NP (for new physics) which is the power of ($1/\Lambda^4$) of the amplitude.
