Hello! I read several books and took courses on quantum mechanics and particle physics and I understood the topics. However I feel that I have only pieces of informations without a global image of what is going on. For example in the particle physics classes we were given Feynman rules without too many details on how to obtain them and we just applied them. I would like something that would help me feel the gap between quantum mechanics and particle physics (with all the main derivation presented), basically I want to really understand how to use quantum mechanics in particle physics. Can you recommend me some (as complete as possible) resources for this? Thank you!
