SUMMARY
The discussion focuses on calculating the self energy amplitude of a sunset diagram with five internal propagators. The user seeks assistance in distributing momentum across these propagators, specifically identifying the variables q and k for the internal loop momenta. A reference to a relevant document, "2loop_selfenergy.pdf," is provided for additional context, which outlines similar calculations for a different configuration. The complexity arises from the increased number of internal propagators compared to simpler diagrams.
