Which Feynman diagram or diagrams include feasible processes?

Click For Summary

Homework Help Overview

The discussion revolves around identifying which Feynman diagrams represent feasible processes in particle physics. Participants are exploring the criteria that define feasibility in this context.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the definition of "feasible" and whether it aligns with "allowed" processes according to the rules governing Feynman diagrams. There are attempts to identify specific diagrams (c and d) as possible, but participants express uncertainty about their correctness.

Discussion Status

The discussion is ongoing, with participants prompted to provide reasoning for their views on the feasibility of certain diagrams. Some guidance has been offered regarding the need for deeper analysis of the rules governing Feynman diagrams.

Contextual Notes

There is mention of previous lessons and research efforts, indicating that participants are working within the constraints of their understanding and available resources on Feynman diagrams.

Hello friends.
I couldn't do it. Which Feynman diagram or diagrams has include feasible process?
 
Physics news on Phys.org
Define "feasible". Do you mean "allowed"? If so, think about what rules the vertices of a Feynman diagram need to satisfy.

Yes. Possible process.

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

Can you explain why you think these processes are possible/not possible?

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.
 
Please take the time to think about and to answer the question posed to you in #4. Your reply is not an answer to that question, but should contain a reasoning based on what you know about Feynman diagrams.

Then, I have to explain all lesson about Feynman diagram )). Thank you.
 
OP tried to delete his original question to close the thread, which is not allowed. Thread is closed now with the OP restored.
