SUMMARY

The discussion centers on the derivation of Feynman rules for scalar Quantum Electrodynamics (QED), specifically referencing "M. Schwartz, Quantum Field Theory and the Standard Model" as a primary resource. Participants emphasize the importance of deriving the rules independently as a valuable exercise, despite the initial confusion expressed by the user seeking help. The conversation highlights the necessity of engaging with the material actively rather than relying solely on external sources for solutions.

PREREQUISITES
  • Understanding of Quantum Electrodynamics (QED)
  • Familiarity with Feynman diagrams and rules
  • Knowledge of quantum field theory principles
  • Proficiency in mathematical techniques used in particle physics
NEXT STEPS
  • Study the derivation of Feynman rules in "M. Schwartz, Quantum Field Theory and the Standard Model"
  • Explore the derivation process for the ##\phi^3## interaction in quantum field theory
  • Review resources on scalar QED derivations from academic papers or textbooks
  • Practice deriving Feynman rules independently to solidify understanding
USEFUL FOR

Students and researchers in theoretical physics, particularly those focusing on quantum field theory and particle interactions, will benefit from this discussion.

Hello! Can someone direct me towards a reading where the Feynman rules for scalar QED are derived? Thank you!

For example, in "M. Schwartz, Quantum Field Theory and the Standard Model". The book has a whole chapter about scalar QED.

Thank you! That is the book I am using actually and I am at that chapter, but in that book the rules are just listed, I would like a full derivation, the same way it is done in previous chapters for the ##\phi^3## interaction.
 
Why don't you derive them yourself? It is a worthwhile exercise and a good opportunity to do it in a case where you have access to the correct result.

I tried, but I am confused at certain steps. I would normally post here what I did so far and ask for help, but I am sure they are derived in some book already (also typing down everything would be quite time consuming as there are many indices).

Sorry, I do not buy this line of reasoning. To me it sounds as if someone posting in the homework forums would say "I would normally solve this problem, but it is difficult so instead I want you to give me the solution". I suggest you do exactly that, post what you have done so far and specify the steps where you are stuck.
