How do I identify which Feynman diagram contributes to the total cross-section?

Asked by Gabriel Vian

Hello, I would like to know a way to identify which Feynman diagram, of a given process, contributes to the total cross-section

I have the following result from my MG simulation:

Graph Cross-section contribution
G1 178
G2 0.32

How do I identify the diagrams corresponding to G1 and G2 ?
