Description of the model & reference

The NTGC model contains the CP-even and the three CP-odd independent dimension-eight operators affecting nTGC and assuming that the gauge boson are coupled to massless fermions or are on-shell. The dimension-eight operator have been truncated to contain only 3-points vertices to fasten the extraction of the UFO and limit it size.

The four-fermion operators are implemented through the exchange of heavy bosons.
