A general formula by LDLTdecomposition for the type-I seesaw mechanism
By performing an approximate spectral decomposition on the inverse mass matrix of the right-handed neutrinos M-1, we obtain a basis-independent formula for the type-I seesaw mechanism. Mathematically, it is based on the generalized Cholesky (or LDLT) decomposition of the symmetric matrix M-1 = LDLT,...
