The mandatory assignment is now out. You have until the end of next week to complete it (and send it to me by mail, no later than May 8). Answers in LaTeX are highly preferred, but feel free to just scan and paste in hand-written Feynman diagrams to save time.
I have marked the two sub-problems that require significantly more calculations than the others with an asterisk. In particular the last one (3e) is not required for a 'pass' -- but I may refer to your solution (and/or ask you to discuss it) in the oral exam if you aim for a very good grade.
