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 WebOverview Anatomy of a Model File Running FeynRules The UFO Format NLOCT - FeynRules beyond tree-level AllYourBases Conclusions Contents 1 Overview 2 Anatomy of a Model File 3 Running FeynRules 4 The UFOFormat 5 NLOCT- FeynRulesbeyond tree-level 6 AllYourBases 7 Conclusions Liam Moore SLAC
