Then, I have to explain all lesson about Feynman diagram )). Thank you.

We have seen lessons, I research again and again my notes. Just the c or d seems possible process on Feynman diagram. I did them unfortunately they're not correct. I still search on Feynman diagrams on internet. Just c and d nearby to be possible.

Yes. Possible process. I see c) or d). But they are incorrect. Interesting I can't explain it.

Hello friends. I couldn't do it. Which Feynman diagram or diagrams has include feasible process?
