The paper
Abstract
The seesaw model of heavy and light Majorana neutrinos and its low-energy effective theory are studied, when the number of heavy neutrinos is equal to or less than the number of light lepton generations. We establish a general relationship between the high-energy parameters and the low-energy observables involving only the light fields. It is shown how low-energy measurements of the properties of light neutrinos suffice a priori to determine all couplings of the unobserved heavy neutrinos. CP violation is present in low-energy processes if seesaw-model leptogenesis creates the matter-antimatter asymmetry of the universe.

Given the fact that the number of primary invariants is equal to that of independent physical parameters, we reach the conclusion that inclusion of just one dimension-five and one dimension-six operator in the effective theory is already adequate to incorporate all physical information about the full theory, including the source of CP violation [ref] .

With the effective operators up to dimension-six (dim-6) or equivalently to the order of $𝒪 (M^-2)$, the tree-level Lagrangian of the type-I SEFT via integrating out right-handed neutrinos at the tree level has been known for a long time, which contains the unique dimension-five (dim-5) Weinberg operator [ref] and two dim-6 operators $^(1)_Hℓ$ and $^(3)_Hℓ$ [ref] .
