Patterns in the fermion mixing matrix, a bottom-up approach
Patterns in the fermion mixing matrix, a bottom-up approach
We first obtain the most general and compact parametrization of the unitary transformation diagonalizing any 3 by 3 hermitian matrix H, as a function of its elements and eigenvalues. We then study a special class of fermion mass matrices, defined by the requirement that all of the diagonalizing unitary matrices …
