Symplectic Symmetry of the Neutrino Mass and the See-Saw Mechanism
arXiv:hep-th/0003260 · doi:10.1103/PhysRevD.62.053002
Abstract
We investigate the algebraic structure of the most general neutrino mass Hamiltonian and place the see-saw mechanism in an algebraic framework. We show that this Hamiltonian can be written in terms of the generators of an Sp(4) algebra. The Pauli-Gursey transformation is an SU(2) rotation which is embedded in this Sp(4) group. This SU(2) also generates the see-saw mechanism.
