The Feynman graphs responsible for tree-level ℛ – ℐ scattering in the toy model. Here solid lines denote ℛ particles and dashed lines represent ℐ particles.
View Image Figure 2:
The 1-particle-reducible Feynman graphs relevant to the definition of the interaction potential. The blobs represent self-energy and vertex corrections.
