SUMMARY
The discussion centers on the legality of Feynman diagrams in particle physics, specifically regarding the interactions of tau and antitau particles. Participants emphasize the hierarchy of interactions: strong > electromagnetic > weak, and the importance of tree-level diagrams over loop diagrams. Key points include the necessity of correcting signs in diagrams and the appropriateness of using photons in certain scenarios. The conversation concludes with a consensus that flipping the right-hand side (RHS) of a diagram can resolve charge issues.
