Coupling
Coupling[label,{indices},order]
denotes the coupling label with a set of indices and a given order in the EFT expansion.
Details and Options
- A coupling can be obtained with the short-cut label[indices] after it was defined using DefineCoupling[label,Indices->{indices},EFTOrder->order].
Examples

Defining a real coupling scaling like 0 powers of the light mass scale:
Afterwards, couplings can be easily written down by writing down their label:
A coupling with flavor indices can be defined by:
This coupling can be obtained with the short-cut:
