We develop a recipe which allows one to recursively and uniquely decouple the large scale from the small scale in mass matrices of the seesaw type, up to any order in the inverse of the large scale. Our method allows one to calculate the mass matrix of the light neutrinos with arbitrary precision. The same method can be applied in the case of quark mass matrices in an extension of the Standard Model with vector-like quarks which have mass terms at a scale much higher than the electroweak scale.

- Flavor structures of charged fermions and massive neutrinos (2019, background): “Such a seesaw formula, which holds up to the accuracy of O(M2 D/M(2) R) [188, 189], is qualitatively attractive as it naturally attributes the smallness of the mass scale of Mν to the largeness of the mass scale of MR as compared with the fulcrum of this seesaw — the mass scale of MD.”
