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.Silviu said:Hello! Can someone direct me towards a reading where the Feynman rules for scalar QED are derived? Thank you!
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.eys_physics said:For example, in "M.

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).Orodruin said: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.
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.Silviu said: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).
Scalar QED stands for Scalar Quantum Electrodynamics, which is a quantum field theory that describes the interactions between a scalar field and the electromagnetic field.
The Feynman Rules for Scalar QED were developed by physicist Richard Feynman in the 1940s. He used them to calculate the probability amplitudes for various particle interactions.
The Feynman Rules for Scalar QED explain how to calculate the probability amplitudes for particle interactions involving scalar fields and electromagnetic fields. They also provide a graphical representation of these calculations using Feynman diagrams.
The Feynman Rules for Scalar QED use mathematical equations to assign numerical values to Feynman diagrams representing particle interactions. These values can then be used to calculate the likelihood of these interactions occurring.
The Feynman Rules for Scalar QED are important because they provide a systematic and efficient way to calculate the probability amplitudes for particle interactions. They are also a crucial tool for theoretical physicists in understanding and predicting the behavior of particles in quantum field theory.
