    "abstract": "The effective field theory (EFT) for a toy model of nucleons interacting via\na short range and a long range Yukawa potential is presented. The scattering\namplitude in the 1S0 channel is calculated up to NNLO using KSW power counting\nscheme. A particular expansion of the amplitude about the pole at low\n(imaginary) momentum is used to derive matching conditions for the EFT\ncouplings. In addition, after imposing constraints from a Renormalization Group\nanalysis, there are no new free parameters in the amplitude at NNLO. Comparing\nthe NNLO phase shifts to the full model we show that the EFT expansion is\nconverging.",
