	Figure 1: 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.
	Figure 2: The 1-particle-reducible Feynman graphs relevant to the definition of the interaction potential. The blobs represent self-energy and vertex corrections.
