WebNov 13, 2024 · $\begingroup$ You seem to confuse FeynCalc and FormCalc, which are two very different codes. Judging from your screenshot, you are trying to use FormCalc and FeynArts, so FeynCalc is not really relevant here. Is that so? Furthermore, providing a link to the lecture you are following would make it easier for people to help. $\endgroup$ – vsht WebMay 3, 2024 · It's a combinatorics question. You can break diagrams down into decision trees (start with a bunch of points, and then decide where to connect, line by line) and you've only written down all diagrams once you've hit every possible branch of the tree, meanwhile obeying constraints like "no duplicate diagrams" (these become symmetry …

For further details of model construction the reader is referred to the respective manuals. 2.2 Linear Combination of Fields Starting from Version 3.5, FeynArts can automatically linear-combine fields, i.e. one can spec-
