Mass eigenstates and mass eigenvalues of seesaw
arXiv:hep-ph/0512373
Abstract
The light neutrino mass spectrum and mixing matrix of seesaw model including three right-handed neutrinos are studied for the most general case. An approximate formulae for mass eigenvalues, mixing matrix, and CP violation of neutrino oscillations are given.
