    "abstract": "The method of effective field theories (EFTs) is developed for the scattering\nof two particles at wavelengths which are large compared to the range of their\ninteraction. It is shown that the renormalized EFT is equivalent to the\neffective range expansion, to a Schroedinger equation with a pseudo-potential,\nand to an energy expansion of a generic boundary condition at the origin. The\nroles of regulators and potentials are also discussed. These ideas are\nexemplified in a toy model.",
