I'm trying to learn Feynman diagrams from Srednicki's QFT book!
Could someone retell and summarize in his or her own words what Srednicki is saying in the three paragraphs after equation 9.11?
(I don't understand what the (2P)!/(2P-3V)! different combinations are, how Feynman diagrams are connected to 9.11, what counting factors are and where to put them,..for short I'm totally confused by what Srednicki is saying here)
thank you
ps: the book is online, but as a PF newbie I'm not yet allowed to post links, maybe someone else could do
