Main Question or Discussion Point
Hello there.
I'm attending an introductory course in particle physics. We're supposed to know how to draw firstorder tree level Feynman diagrams for simple reactions.
I've been struggling to understand the method I should follow in order to correctly draw them.
As I understand it now, we can combine the elementary vertexes of each interaction to get any possible diagram.
Starting from what I've learned by reading Griffiths' book and from my classes, I tried to write some notes about this, and found out that I have some unanswered questions about it.
I attached my pdf file with my notes, with the questions clearly identified in boxes  everything inside a box is a question.
If you could please answer some of those and perhaps see if I got the concepts right, I'd be very grateful.
