- an upper and a lower index is contracted via a Kronecker Delta
- an upper and a lower index is contracted via a Kronecker Delta
- N upper or lower indices of a SU(N) are contracted with the epsilon Tensor
- N upper or lower indices of a SU(N) are contracted with the epsilon Tensor
#### Verifying Index Contractions
If you are unsure about how indices are contracted you can check the output of the function `MakeIndexStructure` which is internally used. Example after loading the THDM-II model:
